7 Most Underrated Horror TV Shows of the 21st Century (So Far)

Television horror is currently enjoying a huge surge in popularity, moving from a small, dedicated fanbase to become a major part of mainstream culture. Shows like The Walking Dead introduced zombie dramas to viewers worldwide, and series like American Horror Story refreshed the genre with its unique, self-contained seasons. Meanwhile, critically acclaimed dramas such as Mike Flanagan’s The Haunting of Hill House demonstrated that horror can be genuinely scary and emotionally resonant, exploring complex family stories alongside supernatural elements. Thanks to these and other shows, television has become a leading platform for compelling horror stories, attracting large audiences and earning widespread recognition.

Even though horror is incredibly popular right now, a lot of truly great series get overlooked. These hidden gems often try bolder, more original ideas and create a genuinely creepy mood, making them different from the more well-known shows. Despite their quality, they don’t get the recognition they deserve, which is a shame for horror fans who are open to discovering something new.

7) Harper’s Island

Harper’s Island was a unique and exciting TV series that lasted one season. It brought the classic slasher horror style – think murder mysteries and suspense – to network television. The story centers around a wedding on a secluded island, seven years after a series of violent crimes shocked the local community. When the wedding guests start to disappear, everyone fears the original killer is back. The show was designed as a 13-week event, promising a death in every episode to keep viewers on the edge of their seats. Combining elements of Agatha Christie-style whodunits with the thrills of Friday the 13th, Harper’s Island worked because it fully embraced its dramatic premise. No character felt safe, and the mystery kept audiences guessing until the very end. While it wasn’t a huge ratings success, its self-contained story makes it a great choice for a binge-watching session if you enjoy classic slasher horror.

6) Fear Itself

Originally intended as a continuation of the popular Masters of Horror series, Fear Itself was a brief but impressive anthology that brought quality horror to NBC in 2008. Each episode featured a standalone, hour-long horror story directed by a well-known genre filmmaker, like Stuart Gordon, John Landis, and Darren Lynn Bousman. The show offered a diverse range of scares, from the terrifying monster in “Eater,” starring Elisabeth Moss, to the dark fairytale of “In Sickness and in Health.” Sadly, the series was canceled before finishing its season due to NBC’s scheduling choices. It was relegated to a summer timeslot and further impacted by coverage of the 2008 Olympics. Despite its short run, Fear Itself remains a collection of creative and unsettling stories, proving what can happen when bold horror isn’t given the right platform.

5) The Enfield Haunting

The story of the Enfield poltergeist has been told many times, including in a well-known horror movie, but the British miniseries The Enfield Haunting is considered the most complete and accurate portrayal. The three-part series is based on investigator Guy Lyon Playfair’s book and dramatizes the alleged experiences of the Hodgson family – a mother and her children – who claimed to be haunted by a malicious spirit in their London home in the late 1970s. What makes this miniseries stand out is its focus on realism and the characters’ emotional journeys. Timothy Spall delivers a compelling performance as Maurice Grosse, a new paranormal investigator still mourning the loss of his daughter, who develops a strong connection with Janet Hodgson (played by Eleanor Worthington-Cox). Instead of relying on cheap thrills, the series builds a sense of unsettling dread by focusing on the emotional struggles of a family facing difficult circumstances.

4) Dead Set

Before creating the dark, futuristic world of Black Mirror, Charlie Brooker cleverly twisted the zombie genre with Dead Set. This five-part series has a simple but brilliant idea: during a zombie outbreak, the Big Brother house – filled with cameras and security – is the safest place to be. The show follows the housemates, the TV crew, and host Davina McCall (playing herself) as zombies take over the world outside, turning the reality show set into a protected haven. Dead Set is a truly frightening horror story with plenty of gore and suspense, but it also cleverly satirizes reality television and our obsession with celebrities. The naive contestants and the jaded producer (Andy Nyman) offer a darkly funny perspective on the apocalypse, making it a horror experience you won’t soon forget.

3) Marianne

The French horror series Marianne quietly premiered on Netflix but quickly gained a reputation for being genuinely scary. The show centers around Emma Larsimon, a horror novelist who realizes the terrifying witch from her books is actually real and haunting her hometown. She’s forced to return and face this demonic force, which possesses people and makes her fictional nightmares come true. Marianne is known for its constant tension, gradually building suspense before delivering truly disturbing visuals and shocking scares. The witch, especially when appearing as the elderly Madame Daugeron, is considered one of the most frightening villains in recent television. Despite positive reviews and a dedicated following, the show was unfortunately canceled after just one season.

2) Channel Zero

For four years, the Syfy anthology series Channel Zero turned popular internet horror stories – known as “creepypastas” – into some of the most original and unsettling horror on TV. Each season presented a completely new story inspired by a different online legend, like the tale of the tooth-stealing Skin-Taker in “Candle Cove” or the strange building in “No-End House.” The show was great at turning these viral stories into gripping dramas with well-developed characters, all while creating a consistently eerie and dreamlike mood. Because each season was self-contained, Channel Zero could explore different types of horror, making it consistently imaginative and truly frightening.

1) The Terror

Inspired by Dan Simmons’ novel, the first season of The Terror is a brilliantly crafted historical horror series that didn’t get the attention it deserved when it first aired. It reimagines the true story of Captain Sir John Franklin’s ill-fated Arctic expedition in the 1840s, where his ships, the HMS Erebus and HMS Terror, became stuck in the ice. As the crew struggles with hunger, sickness, and growing fear, they’re hunted by an unknown creature in the frozen wilderness. The Terror skillfully combines the tension of a survival story with chilling supernatural horror. The incredible acting, especially from Jared Harris as Captain Francis Crozier and Ciarán Hinds as Sir John Franklin, grounds the story in real emotion, making the horror even more impactful. It’s a haunting, visually stunning, and deeply frightening series that is quickly becoming a modern classic.
