The Best Sci-Fi Shows to Start Now, and Which Ones Actually Finish
By Jordan A. · · Updated · 5 min read
Checked September 9, 2026. The single most useful thing a science fiction list can tell you is not whether a show is good. It is whether the show has an ending, because this genre gets canceled mid-sentence more than any other, and starting a five season mystery that stops at season four is a specific kind of misery.
So everything below is sorted into finished, still running, and canceled without a landing. Each entry gets its platform of origin, its years and its season count. Where each streams today changes, so the title page on BingeNext shows current US options rather than a guess.
Finished, with a real ending
The Expanse (Prime Video, 2015 to 2022, six seasons) is the best hard science fiction series made for television. A missing girl, a warship, and a solar system where Earth, Mars and the asteroid belt all have incompatible grievances. It ran six seasons and stopped there, which leaves several books unadapted but gives the show a genuine conclusion. Choose it if you want physics that behaves and politics that make sense. The first season is the weakest, which is worth knowing before you judge it.
Dark (Netflix, 2017 to 2020, three seasons) is a German time travel series set in one town across several generations, and it is the rare show that planned its ending from the first episode and hit it. It shares nothing with the space end of the genre. The difference is that it demands your full attention and a chart. Choose it if you want a puzzle that actually resolves. Watch it in German with subtitles.
Battlestar Galactica (Syfy, 2003 to 2009, four seasons) is still the template for serious genre television made on a budget, and its post-attack politics have aged strangely well. The difference from everything newer is the episode count, since seasons ran long in that era. Choose it if you want something to live in. The finale divides people, but it is an ending.
Fringe (Fox, 2008 to 2013, five seasons) starts as a monster-of-the-week procedural and quietly becomes a parallel-universe family tragedy. It shares the network structure of its era. The difference is that it earned its final season and used it. Choose it if you want a long-running show that knew it was ending.
Pantheon (2022 to 2023, two seasons) is an animated series about uploaded human consciousness that got mishandled by its original broadcaster and then found an audience on Prime Video. It is complete, it is smarter than most live-action shows on this list, and almost nobody has watched it. Choose it if you want the recommendation you can actually surprise people with.
Devs (FX, 2020, one limited season of eight episodes) is Alex Garland on determinism, a quantum computing company and a very quiet kind of menace. It is eight episodes and it concludes. Choose it if you want the shortest complete watch here.
Scavengers Reign (2023, one season of twelve episodes) is animated, near-wordless in stretches, and about a crashed crew on a planet whose biology is genuinely alien rather than dinosaurs with extra eyes. It has not continued past its single season, but the story it tells is complete. Choose it if you want the most beautiful thing on this list.
Still running, so you are signing up for a wait
Severance (Apple TV+, 2022 onwards) splits employees into a work self and a home self who never meet, and it is the best-directed show in the genre right now. The difference is the gap between seasons, which has been long. Choose it if you can tolerate waiting.
Silo (Apple TV+, 2023 onwards) is ten thousand people in a buried silo where asking why is a capital offence. It shares Severance's corporate dread. The difference is that it is a mystery box, so patience is required. Choose it if you like a slow reveal.
For All Mankind (Apple TV+, 2019 onwards) is an alternate history where the Soviets landed on the Moon first and the space race never ended, jumping roughly a decade every season. Choose it if you want optimism, which is scarce here.
Foundation (Apple TV+, 2021 onwards) is the loosest possible adaptation of Asimov and much better as its own thing: a thousand year empire, a mathematician who predicts its fall, and a genetic dynasty of cloned emperors that is the best part of the show. Choose it for spectacle. Apple has not announced a premiere date for a fourth season, so treat any specific date you see for it as speculation.
Star Trek: Strange New Worlds (Paramount+, 2022 onwards) is the return to episodic Star Trek, one problem per week, and it is the most purely enjoyable show here. Choose it if serialised despair is not what you need.
3 Body Problem (Netflix, 2024 onwards) adapts Liu Cixin's novel with a first contact that plays out across centuries. Choose it if you want the biggest ideas. Be aware Netflix has a record with this kind of show, so the risk of it stopping early is real.
Canceled without landing
Westworld (HBO, 2016 to 2022, four seasons) ran four seasons before HBO canceled it in November 2022, and it stops in the middle of a plot. Season one is one of the best things HBO has made. Everything after it is a decision you should make with your eyes open. Choose it only if you are willing to watch season one and stop.
Where to start
If you want the best complete series in the genre, start with The Expanse. If you want eight hours and a real ending, start with Devs. If you want something currently airing that is worth the wait, it is Severance. And if you want the one that will make you feel something unexpected, watch Scavengers Reign.
If you would rather sort by what you already love than by what a list says, put two favorites into BingeNext TV recommendations and you will get ranked picks with a reason for each and a note on where they stream. It takes about a minute.
