2025’s 25 best drama series – from Slow Horses to Adolescence

by

Year after year, TV dramas continue to prove they’re a remarkably effective way to explore and question the issues facing our society.

In 2025, television series truly stood out. From shows based on real events that sparked important conversations, to entertaining stories that explored complex themes, many captivated viewers and stayed with them even after they finished watching.

These shows aren’t just well-made; they’re boldly ambitious. They dared to take risks with their storytelling, tackling difficult subjects and pushing creative boundaries. From revisiting historical traumas to addressing current fears, and reinventing established TV structures, these dramas consistently asked important questions about power, fairness, who we are, and what we owe each other – whether the setting was a battlefield, a corporate office, or an interrogation room.

Our critics have chosen the 25 best dramas of the year – the shows that truly captivated us. These series sparked discussions, stirred strong emotions, provided comfort, and proved why television can still be exceptional. From suspenseful mysteries to important real-life stories, this is TopMob‘s official list of the year’s most compelling dramas.

25. Suspect: The Shooting of Jean Charles de Menezes

Where to watch: Disney+

Following the 2005 London bombings, electrician Jean Charles de Menezes was tragically shot and killed by police officers while on his way to work. This four-part drama powerfully portrays the series of mistakes that led to his death on July 22, 2005, focusing on the actions of key figures like Ian Blair (played by Conleth Hill), Brian Paddick (Russell Tovey), and Cressida Dick (Emily Mortimer). The series, reminiscent of the excellent BBC Two documentary 7/7: the London Bombings (available on iPlayer), highlights how quickly misinformation spread after the event, and how many inaccuracies persist even today. It’s hoped this drama will help to correct those false narratives. – Frances Taylor

24. Trespasses

Where to watch: Channel 4

In 1975 Northern Ireland, a young Catholic teacher named Cushla (Lola Petticrew) falls for Michael (Tom Cullen), a married Protestant barrister. Their instant connection is complicated by the deep religious and political divisions of the time, making a relationship nearly impossible. Based on Louise Kennedy’s novel, Trespasses powerfully depicts the immense pressure and constant danger of life in a divided society. The film features strong performances from Gillian Anderson as Cushla’s tough, alcoholic mother, and Martin McCann as her brother, adding to its impactful and dramatic story. – Jane Rackham

23. Smoke

Where to watch: Apple TV

This compelling drama, inspired by true events, unfolds gradually, especially after a major reveal at the end of the second episode that completely changes the story. Taron Egerton and Dennis Lehane, who previously collaborated on the acclaimed series Black Bird, team up again here, with Egerton playing Dave Gudsen, an arson investigator tracking down serial arsonists in the Pacific Northwest. Alongside Jurnee Smollett and Rafe Spall as his uneasy partners, the beautifully shot series consistently delivers unexpected twists and turns through its flawed, yet captivating, characters. – Jacke Seale

22. Bookish

Where to watch: NOW

The period immediately following World War II created a breeding ground for crime, as societal values became blurred and cities lay in ruins. With resources scarce, some people saw opportunities for personal gain, and even those hailed as heroes often carried hidden burdens from their wartime experiences. This complex world is the setting for the story of Gabriel Book (Mark Gatiss), a compelling character full of contradictions. He runs a bookshop in London while also working as an amateur detective, and he’s a married man (played by Polly Walker as Trottie) secretly leading a double life as a gay man – a particularly insightful detail that allows for a delicate and moving portrayal of his personal struggles. – David Brown

21. Hacks

Where to watch: NOW

You might not know it, but “Hacks” is one of the funniest comedies on TV. It’s won major awards like Emmys and Golden Globes and has a dedicated fanbase, but hasn’t yet become a mainstream hit in many regions. Jean Smart is brilliant as Deborah Vance, a veteran comedian whose career was fading until she teamed up with young writer Ava Daniels (Hannah Einbinder). By the end of season three, Deborah had finally achieved her dream of hosting a late-night talk show, and Ava was thriving as the show’s head writer. So what’s next in season four? Plenty of trouble, it seems, as Ava tries to outsmart Deborah – a master of the game who’s been playing it for 50 years and always wins. – Frances Taylor

20. Reacher

Where to watch: Prime Video

The latest season of this thrilling series, based on Lee Child’s books, delivers another action-packed ride. Alan Ritchson returns as Jack Reacher, a former military police officer who goes undercover to take down a criminal organization. Expect intense scenes – including a dangerous swim in rough waters, a resourceful assassination using everyday office items, and a brutal fight with an opponent who rivals Reacher in size. The show maintains its signature blend of exciting action, witty dialogue, and a touch of romance, this time featuring a compelling dynamic with DEA agent Susan Duffy, played skillfully by Sonya Cassidy. – Jack Seale

19. Nine Bodies in a Mexican Morgue

Where to watch: BBC iPlayer

This crime drama by Anthony Horowitz, a truly skilled writer, blends elements of Lost and Agatha Christie’s And Then There Were None. The story begins with a plane crash in the Mexican jungle, and then survivors begin to disappear, killed by someone among them. It’s a classic murder mystery setup – one that would feel right at home with Christie’s glamorous style. However, by placing the story in a harsh and unforgiving setting, Horowitz seems to be making a point: while murder mysteries are puzzles to be solved, the act of murder itself is rarely pretty.

18. Your Friends and Neighbours

Where to watch: Apple TV

17. Untamed

Where to watch: Netflix

Eric Bana stars in this exciting mystery thriller, but the stunning scenery of Yosemite National Park is almost a character itself. While special agent Kyle Turner knows the park well, the film suggests that its untamed and rugged nature will constantly challenge his attempts to solve a difficult murder case. – David Brown

16. Unforgivable

Where to watch: BBC iPlayer

Award-winning writer Jimmy McGovern is known for addressing tough topics, and his latest work is no exception. It powerfully portrays the long-lasting impact of a child’s sexual abuse at the hands of his uncle. The drama features difficult but realistic scenes of emotional pain, self-loathing, and hopelessness, brought to life by strong performances from Bobby Schofield, Anna Friel, and Anna Maxwell-Martin. It also challenges viewers to consider complex questions about forgiveness, even for someone who recognizes the monstrous nature of their actions, as the abuser himself admits to being reprehensible. – Jane Rackham

15. House of Guinness

Where to watch: Netflix

14. The Newsreader

Where to watch: BBC iPlayer

This Australian drama brilliantly captures both the excitement and the pressures of being famous. Despite flying under the radar for three seasons, it’s well worth watching. Though set in the cutthroat world of 1980s Australian news, the show explores universal human weaknesses. In this final season, news anchor Dale Jennings (Sam Reid) struggles with devastatingly negative audience reviews. His boss, Lindsay, cruelly neglects his duty to support him, leaving fellow host Helen Norville (Anna Torv) to step in and help her on-screen competitor. – David Brown

13. Squid Game (Netflix)

Where to watch: Netflix

Following a somewhat confusing second season focused on a shooting competition, the popular Korean series – centered around a mysterious contest where players compete until only one survives (and by ‘survive,’ we mean they often die) – returns to its original premise for its third and final season. Seong Gi-hun (Lee Jung-jae) is back, attempting to win the huge prize money while also trying to sabotage the game from within to bring it down. The added challenge of a pregnant contestant keeps things interesting, and the season successfully reinvents itself, consistently surprising viewers and culminating in a memorable ending that will stay with you. – Jack Seale

12. The Bear

Where to watch: Disney+

After years of wildly different reactions – from praise to criticism – Christopher Storer’s compelling drama The Bear is back for a fourth season and arguably better than ever. While still centered on the high-end Chicago restaurant and chef Carmy (Jeremy Allen White), this season focuses less on the daily struggles of the business and more on the characters’ emotional lives. Storer has built a richly drawn family of characters, and this season, viewers will find themselves deeply invested in their journeys. – Jack Seale

11. This City Is Ours

Where to watch: BBC iPlayer

It’s understandable if you stopped watching this drama after the first few episodes. Initially, it seemed like just another gangster show – some even called it a “Scouse Sopranos” – but stick with it, and you’ll find a complex story with deeply flawed, yet compelling, characters. Plus, there’s a memorable dance sequence – many people tried to recreate it! The series stars Sean Bean and Julie Graham as the leaders of the Phelan crime family. However, James Nelson-Joyce, who plays Michael, really stands out. He delivers a captivating performance as a man struggling with a difficult past and present while trying to build a better future with his partner, Diana (Hannah Onslow). – Frances Taylor

10. Code of Silence

Where to watch: ITVX

Alison, who works in a police canteen and is a skilled lip-reader, is recruited by detectives to help them understand surveillance footage of a planned robbery. While she’s intelligent and capable, Alison becomes deeply involved in the case, putting herself in danger. The script, written by Catherine Moulton, powerfully highlights how often deaf people are overlooked and misunderstood. The film uses subtitles that initially seem fragmented, but become clearer as Alison deciphers the conversations, giving viewers insight into the everyday struggles faced by the deaf community. It’s a compelling crime drama with a meaningful message, featuring a talented cast including Andrew Buchan. – Jane Rackham

9. Death Valley

Where to watch: BBC iPlayer

This cozy mystery series is elevated by a wonderful performance from Timothy Spall, who plays John Chapel, a former TV detective now living a quiet, secluded life in Wales. When a shooting occurs, Detective Sergeant Janie Mallowan tries to enlist his help, using humor to coax him out of his shell. John, however, feels he’s beneath the investigation, viewing the work as a silly demotion from his former career – like an Olympic athlete being asked to participate in a children’s game. – David Brown

8. Prisoner 951

Where to watch: BBC iPlayer

Nazanin Zaghari-Ratcliffe’s ordeal began when she was arrested at the airport in Iran on her way back to Britain with her young daughter, after a visit with her parents. The Revolutionary Guard detained her without explanation, falsely suggesting she was a spy. The real reason for her imprisonment was to pressure Britain into paying a long-standing debt to Iran. Her family endured six years of separation before finally being reunited. The film powerfully portrays the fear, helplessness, and frustration experienced by Nazanin (played by Narges Rashidi) and her husband Richard (Joseph Fiennes) – Nazanin’s time in solitary confinement and being moved between prisons blindfolded, contrasted with Richard’s tireless campaigning for her release. It’s a deeply disturbing and unjust story. – Jane Rackham

7. Dept Q

Where to watch: Netflix

I’m totally hooked on this new show! Matthew Goode is just perfect as a brilliant but troubled detective – he’s got this amazing dry wit and you can tell he’s carrying a lot of baggage. The show is set in this really atmospheric, almost creepy basement office in Edinburgh, and he works with this fantastic team of misfits. They’re basically a cold case unit, and in the first case, they’re looking into the disappearance of a really driven prosecutor. It reminds me a lot of Slow Horses with that whole ‘underdogs fighting the system’ feel, but it has its own unique, slightly gothic vibe that’s really captivating. And Alexej Manvelov as Akram Salim? He completely steals every scene he’s in! Leah Byrne is great too, as this really enthusiastic DC Rose Dickson.

6. Down Cemetery Road

Where to watch: Apple TV

With Emma Thompson and Ruth Wilson starring, this drama – based on the first novel by the creator of ‘Slow Horses’ – was always likely to be good. When an explosion rocks the home of art restorer Sarah (Wilson) near Oxford, she crosses paths with cynical investigator Zoë (Thompson). They soon uncover a risky government plot, forcing them to work together and perhaps even form a connection to stay alive. Clever, bold, and full of funny and frightening characters, it’s a thoroughly enjoyable watch. – Jack Seale

5. A Thousand Blows

Where to watch: Disney+

Steven Knight, the creator of Peaky Blinders, is back with another story inspired by true crime, this time focusing on a group of female pickpockets in Victorian England. The story centers around the strong-willed Mary Carr (played by Erin Doherty) and her unlikely partnership with Jamaican immigrant Hezekiah Moscow (Malachi Kirby), whom she trains as a bare-knuckle boxer. This puts them on a path to conflict with the area’s boxing champion, Sugar (Stephen Graham). Expect witty conversations, exciting fight scenes, and a sensitive portrayal of those struggling in society. – Jack Seale

4. Slow Horses

Where to watch: Apple TV

Tech expert Roddy Ho (Christopher Chung) is surprisingly having a good time – he’s even got a girlfriend! His colleague, Shirley (Aimee-Ffion Edwards), is worried this isn’t what it seems and tries to convince their boss, Jackson Lamb (Gary Oldman). This sets the stage for the fifth installment of the Slough House spy series, which involves a series of murders at a shopping center and a heated London mayoral election. As always, the show expertly balances serious drama with clever comedy, delivering both thrills and laughs. – David Brown

3. Blue Lights

Where to watch: BBC iPlayer

This season of the critically acclaimed Northern Irish police drama expands its focus, moving beyond street crime and religious conflict to explore the powerful figures controlling Belfast in 2025. The team also sees changes, with Stevie O’Neill (Martin McCann) promoted to sergeant. Despite these shifts, the series continues to deliver intensely dramatic, life-or-death scenarios. Even seasoned viewers will find these confrontations gripping, unpredictable, and incredibly tense, keeping them on the edge of their seats. – David Brown

2. I Fought the Law

Where to watch: ITVX

Sheridan Smith gives an incredible performance as Ann Ming, the mother who tirelessly fought for a change in the law so the man who killed her daughter, Julie Hogg, could be tried again. This isn’t a typical legal drama; it mainly focuses on the devastating aftermath of Julie’s murder in 1989. The story begins with Ann discovering Julie’s body and the initial, poorly handled police investigation, then follows the family’s years of suffering as they sought justice in court. While you’ll be inspired by Ann’s strength and determination, be prepared for a deeply emotional and heartbreaking experience. – Jane Rackham

1. Adolescence

Where to watch: Netflix

Critics at TopMob often have different opinions, but everyone agreed on the best drama of the year. This Netflix series, which won Emmys for Stephen Graham, Erin Doherty, and Owen Cooper (the youngest male winner ever), had a significant impact beyond entertainment. It sparked important conversations about serious issues like knife crime, violence, and misogyny among teenagers, even reaching the attention of police and government officials. The show’s creator, Jack Thorne, was asked to speak to Parliament, and Keir Starmer suggested it should be shown in schools.

The new series benefits from a fantastic combination of creative talent, with both Thorne and Graham writing the script. Philip Barantini, the director known for his seamless “one-shot” technique (previously seen in Boiling Point), returns to collaborate with Graham, filming each episode as a single, continuous scene in real-time. This bold and meticulously planned approach creates a gripping sense of tension and confinement as the story unfolds. The series centers on Jamie (Cooper), a 13-year-old boy arrested after a classmate is murdered. He insists on his innocence to his father, Eddie (Graham), before questioning begins, but the truth remains unclear. – Frances Taylor
