4 Sci-Fi Shows That Got Better Every Year

by

It’s common for even great TV shows to have one weak season. And it’s frustrating when a show you love seems to lose its way in the final season, ultimately damaging its legacy. Consistently delivering high quality throughout a show’s entire run is a real challenge.

It is possible to find truly unique sci-fi shows. A few have genuinely earned that distinction – from a memorable ’90s series that always did its own thing, to one that built a rich and detailed world that guided every story it told. And sometimes, even shows that sparked debate among fans managed to consistently improve over time.

In Terms of Serialized Storytelling on Network TV, Babylon 5 Was Ahead of Its Time

It’s now common for streaming shows to unfold like novels, carefully building characters and storylines over several episodes instead of immediately relying on action and excitement. This wasn’t the case with network TV in the 1990s, where shows needed to grab viewers right away. However, things shifted, and this new approach completely changed how television was made.

J. Michael Straczynski remarkably persuaded Warner Bros. Television to support his five-year vision for Babylon 5, a science fiction story set on a space station focused on galactic diplomacy and commerce. He also wrote the vast majority of the show’s episodes – 92 out of 110 – treating each one as a piece of a larger, ongoing story about war between species, internal conflicts, and the struggle to prevent Earth from becoming a dictatorship. Studio executives were concerned that the complex storyline would be too much for viewers to follow each week. However, Straczynski had faith in the audience, and he delivered a series that reached incredible emotional and narrative peaks in its later seasons, becoming something truly special.

Ultimately, Babylon 5 stands as proof of careful planning and J. Michael Straczynski’s ability to follow through on his ideas. This level of long-term storytelling was unusual for television then – and remains so today – and it’s what truly sets Babylon 5 apart. The show consistently improved over its run because Straczynski deliberately designed it that way, and he had the support needed to bring his ambitious vision to life.

Fringe’s Parallel Universe Mythology Expanded Beautifully Across Five Seasons

When Fringe first aired in 2008, it stood out from other sci-fi shows. Instead of focusing on aliens or the supernatural, each episode explored unusual scientific experiments. Throughout its five seasons, the show developed a more connected storyline, though it occasionally featured self-contained episodes. Eventually, Fringe revealed a complex story centered around a parallel universe, where strange occurrences happened at points where the two universes overlapped.

After a major plot twist reshaped the series, we began to see characters from different worlds interacting more and more, which proved to be incredibly interesting. The show then fully embraced science fiction for its final two seasons. Season four took place in an alternate reality, and season five depicted a dark future where the mysterious Observers – who had been watching events unfold since the beginning – had decimated the human population.

Honestly, by the later seasons, Fringe had changed a lot from its beginnings and a lot of people stopped watching. But for those of us who stayed with it, it was so worth it! It became one of the smartest, most ambitious sci-fi shows I’ve ever seen. And what’s really amazing is that even until the very last episode, the show’s complex story still made sense – something even The X-Files couldn’t always pull off.

Legends of Tomorrow Began as a Wonky Superhero Show, But Ended As a Sci-Fi Treat

When DC’s Legends of Tomorrow first started, it felt a bit chaotic because it was essentially a place for characters who didn’t quite fit into The CW’s other superhero shows. However, it was still enjoyable to watch characters like The Atom, White Canary, Martin Stein, and Captain Cold get caught up in a time-travel adventure centered around the immortal villain Vandal Savage.

Initially, the show had trouble finding its unique voice and seemed to take its ridiculous concept too seriously. But then, something rare happened: the creators acknowledged their mistakes. Over the following seasons, the show steadily became much funnier, embracing and amplifying the wildness of the Legends’ time travels.

Despite a rocky start, Legends of Tomorrow managed to last for seven seasons – a remarkable feat! Rather than trying to fit neatly into the Arrowverse, the show leaned into its quirky nature, and it actually got better with each season. It can be a bit confusing for those new to superhero or sci-fi shows, but the consistent improvement in quality is well worth it.

Some Fans Think Westworld Got Worse Over Time, But it Actually Got Better

Many fans see the path of HBO’s Westworld as a warning to other shows. While the expensive series was a huge cultural hit with its first season, it was canceled before its creators, Jonathan Nolan and Lisa Joy, had planned, due to falling ratings. By the final season, viewership had dropped a dramatic 81% from the premiere. Most believe the show lost its way, becoming too complex and alienating to general audiences as it delved deeper into challenging sci-fi ideas like artificial intelligence, time travel, simulations, and dark futures.

Those who enjoyed the show from the beginning found it consistently strong. It didn’t decline in quality; instead, it became more complex, unusual, and distinctive with each season. This resonated more with typical science fiction fans than shows focused on wealthy characters and advanced technology. The writing by Nolan and Joy reached its peak in seasons three and four, and the performances from Evan Rachel Wood, Tessa Thompson, Thandiwe Newton, and Jeffrey Wright were outstanding as their characters developed and changed.

Ed Harris’s portrayal of the Man in Black perfectly captures what fans love about Westworld and what frustrates its critics. Throughout the show’s four seasons, Harris openly admitted he didn’t fully understand his character’s journey. Surprisingly, this lack of understanding actually enhanced his performance. As the showrunners, Nolan and Joy, took bigger risks with the character, Harris became even more compelling and unsettling.
