5 Sci-Fi Shows That Shaped the 2010s — 360 Episodes You Can't Skip
TV has always loved sci-fi. Rod Serling's The Twilight Zone didn’t just blaze a trail; it set the standard, and a wave of genre series has been pushing the medium further ever since.
TV sci-fi never really leaves; it just mutates with the times. The 60s had The Twilight Zone changing the game while Star Trek and Doctor Who were getting their bearings. Every decade since has tried its own spin. The 2010s were especially wild, thanks to streamers barging into original programming and tilting the table. A lot of the best genre swings didn't always win ratings wars, but they absolutely bent the medium. With the 2020s still shaking out, here are the five shows from the 2010s that actually moved the needle.

5) Westworld
Total episodes: 36
Two big takeaways landed the moment Westworld arrived. First, HBO proved it could be more than the Game of Thrones channel and still deliver capital-A Appointment TV in a totally different lane. Second, a dusty old genre idea could be rebuilt from the ground up when you give it the time, budget, and ambition that prestige TV allows. The show's reinvention of a forgotten property wasn't perfect, but it showed how a remake can find its own identity instead of just wearing someone else's skin.

4) The Flash
Total episodes: 184
Superheroes owned movie theaters in the 2010s. On TV, Arrow technically kicked off The CW's shared universe, but The Flash is the series that went for broke. Over nine seasons it didn't just parade an army of DC heroes and villains through Central City; it took comic arcs fans already loved and actually made them work in live-action. Time travel? Constant. Parallel Earths? Weekly. The show normalized the multiverse on television long before the MCU made it the center of its big-screen strategy, and its sci-fi toolkit is what let the Arrowverse's bigger, crazier crossover stories happen at all.

3) Star Trek: Discovery
Total episodes: 65
Announced in November 2015 as Trek's first new TV show in a decade, Discovery launched not on broadcast but on the newborn CBS All Access service. That alone was a line in the sand for how franchises would live in the streaming era. Behind the scenes, it was messy: major creative changes, including Bryan Fuller leaving, shifted the show's direction. Alex Kurtzman stepped in as the primary creative voice, the show pulled strong viewership, and that win turned Kurtzman into Paramount 's point person for the brand — to the frustration of plenty of fans. He wound up executive producing all six Star Trek series that followed Discovery's debut. And even now — with the most recent series, Star Trek: Starfleet Academy, already getting canceled — Kurtzman remains attached to Trek's future. Like it or not, none of that happens without Discovery breaking the seal.

2) Black Mirror
Total episodes: 33 (plus a movie)
Channel 4 dropped Black Mirror on December 4, 2011 with a premiere that made jaws hit the floor and made it very clear the show wasn't afraid of brutal endings. Instant must-watch. The ripple effect was huge: anthology TV — dormant for ages — suddenly had momentum again, big enough that The Twilight Zone came back to television after a sixteen-year nap. On top of that, Charlie Brooker's scenarios about tech and how we'd twist it for the worse kept coming true in uncomfortable ways. The show warned us; we mostly shrugged and kept scrolling.

1) Stranger Things
Total episodes: 42
At first, some people waved it off as Spielberg-meets-King karaoke. Then Stranger Things detonated into a full-on phenomenon. Two reasons it matters most for the decade: One, it gave Netflix its first real franchise — and they ran with it, from an animated spinoff to a prequel play on Broadway, with more on the way. Two, it slammed the accelerator on 80s nostalgia. Yes, the era was already back in the cultural mix, but the show made it the main course: more period-set projects, old brands resurrected, and a very welcome career renaissance for Winona Ryder. Whatever you think of the pastiche, the impact is undeniable.
Bottom line: the 2010s proved sci-fi on TV still had new tricks — and a willing audience — even as the platforms and power players changed. These five shows didn't just ride the wave; they helped make it.
