5 Cancelled Sci-Fi Masterpieces That Ended Far Too Soon

by

As a sci-fi fan, it’s incredibly frustrating how often our shows get cancelled. It seems like because these shows are often a bit different and really expensive to make – all the special effects and detailed worlds add up – networks and streamers are quick to pull the plug, even if we’re passionately devoted. Every now and then, they take a chance and it pays off with a complete, satisfying story, like with Dark on Netflix. But way more often, we’re left with unanswered questions and storylines that just end abruptly. It’s a real pattern for the genre.

It really pains me to say it, but some of these shows were truly incredible – genuine masterpieces, even. Despite not always getting the endings they deserved, I – and so many others – still adore them. They built such amazing worlds, filled with compelling characters and fascinating stories. There were even times when fans rallied so passionately that a show got another shot, but sadly, every single one of these brilliant sci-fi adventures was cut short before it could truly shine.

5) The OA

Okay, so The OA is this show Brit Marling and Zal Batmanglij made for Netflix back in 2016. Marling also stars as Prairie Johnson, a woman who goes missing blind and then shows up seven years later… able to see! It’s a really emotional ride, but honestly, it’s also super weird and confusing at times. There’s a lot of near-death stuff, talk of other dimensions, and… well, a lot of interpretive dance. They don’t explain anything directly, which drove some people crazy, but that’s also what made it so unique and, for me, so compelling. It definitely wasn’t for everyone, but it was unlike anything else I’ve ever seen.

Despite initial plans for a five-season run, the series was unfortunately cancelled after only two seasons. Netflix cited viewership numbers as the reason, explaining that the show’s complex and gradual storytelling made it hard to gain a wider audience. However, the second season was just starting to explore its full potential with an expanded storyline, and many believe that with the planned five seasons, it could have become a truly classic show. The early cancellation left many important questions and plotlines unanswered. While the two existing seasons are brilliant on their own, it’s a shame we never got to see how the whole story would unfold.

4) Jericho

Jericho, a 2006 CBS series, took place in a small Kansas town where people were trying to rebuild their lives after nuclear attacks hit major U.S. cities. Starring Skeet Ulrich, the show stood out for its realistic portrayal of post-terrorism anxieties and its thoughtful exploration of what life would be like with limited resources. While not a large-scale spectacle, Jericho was a down-to-earth post-apocalyptic story that attracted a dedicated fanbase.

CBS initially cancelled the show Jericho after only one season. However, they reversed their decision due to a passionate fan campaign – fans sent executives tons of peanuts, referencing a memorable line from the series. Although Jericho returned for a shorter second season, it wasn’t enough to save it. The storylines felt hurried, major plot points weren’t resolved, and the show was cancelled for good. While the story continued in comic books, Jericho ultimately deserved a longer run on television.

3) Firefly

Joss Whedon’s beloved space western, Firefly, centered on the adventures of the Serenity’s diverse crew as they struggled to survive in a galaxy recovering from a civil war. Led by Nathan Fillion as Captain Malcolm Reynolds and featuring a talented cast including Gina Torres, Alan Tudyk, Morena Baccarin, and Summer Glau, the show explored themes of found family, resonating with both the characters and its devoted fans.

Fox famously aired episodes of Firefly out of sequence and then cancelled it after only 14 episodes, preventing its complex storyline from fully developing. While a devoted fanbase and their efforts resulted in the movie Serenity, which offered some resolution, it couldn’t make up for the many seasons of character development that were lost. Like other shows on this list, Firefly wasn’t cancelled because it was poorly made; it was simply mishandled by the network. Fans remain upset about this decision even today, over two decades later.

2) The Expanse

I’ve been completely captivated by The Expanse! It started on Syfy and is based on the amazing novels by James S.A. Corey. What I love most is how it builds this incredibly detailed future where humans have colonized the solar system, but are really divided between Earth, Mars, and those living in the Belt. Created by Mark Fergus and Hawk Ostby, the show really stands out because it feels so realistic – the science is solid, and the characters, like James Holden and the brilliant Chrisjen Avasarala, are forced to make incredibly difficult choices, and it’s fascinating to watch how they navigate it all.

I was so bummed when Syfy cancelled The Expanse after just three seasons, but then Amazon swooped in and saved the day! And honestly, it actually improved with their support – the show really got to shine. It was heartbreaking when it ended after six seasons, though. A lot of us fans think it was probably because it was getting expensive to make and the books jumped ahead in time a lot. The finale was really good, a solid ending, but it still didn’t cover the whole book series. We’re still hoping against hope that Amazon will give us a Season 7 to finish the story!

1) Farscape

Farscape is a truly original science fiction series, standing out for its imaginative storytelling and incredible creature effects created by Jim Henson’s Creature Shop. The show, starring Ben Browder as astronaut John Crichton and Claudia Black as Aeryn Sun, masterfully blended chaos, romance, and thought-provoking themes, all while building rich and compelling characters. Even though it first aired in 1999, Farscape remains a beloved favorite among sci-fi fans for its willingness to be both playful and deeply serious.

Despite being a critical success and running for four strong seasons, Farscape was surprisingly cancelled before its planned fifth season, leaving fans frustrated with an unresolved cliffhanger. The strong reaction from viewers did lead to a follow-up miniseries, The Peacekeeper Wars, which provided some closure – at least, according to dedicated fans known as “Scapers.” However, the cancellation still felt abrupt. Farscape was at its best when it ended, and though it received more resolution than many shows, it’s still remembered as a prime example of a great sci-fi series cut short.
