Best sci-fi TV shows: 15 sci-fi series to binge-watch today
Simon Brew
23 June 2020

We are currently in another golden age of science fiction on the small screen, which makes picking a handful of shows for this best sci-fi series list rather tricky.

The contemporary explosion in science fiction television, aided by no shortage of available boxsets (most of which reside on streaming services rather than in physical boxes, but let’s not get picky), is staggering for those who were left in the '70s and '80s clawing at the few morsels being offered.

UPDATE: The most recent new addition to our list is The Leftovers and the fantastic The Mandalorian. Both are very different slices of sci-fi but both tackle the genre with aplomb.

But as movie special effects pathfinding work has trickled down, and television has allowed writers to go to darker places, the result is a selection that’s seen television firmly wrestle the sci-fi mantle from the big screen.

Here are 15 to get you started, but note that science fiction television tends to generate ‘disagreement’ and ‘debate’.

Please be assured that just because there are 15 on this list, it doesn’t mean that others are not available…

1. The Expanse

Stream from Amazon

We are lucky to have The Expanse. The show was nearly cancelled until one of its biggest fans saved it from cancellation. It wasn't just any fan, buy Jeff Bezos who happens to own Amazon. Since being saved the show, about a human colony on the outreaches of space, has gone from strength to strength - pushing its political overtones while keeping the series completely engrossing.

2. Battlestar Galactica

Stream Now (Prime Video)

If you’re looking for a show that intertwines those dinner party favourite conversations of religion and politics, not least the influence of one on the other, the 2004 reboot of Battlestar Galactica – for around 60% of its run – does just that in terrifyingly authentic style. It goes on to follow a narrative path that’s either incredibly bold or just plain nuts depending on your perspective. It’s also notable for getting around TV swearing censors, in full on Father Ted style, by introducing its own special cuss word.

3. Star Trek: TNG

Buy now from Amazon

There has been something of a revival for Star Trek: TNG and it's all thanks to Picard which is currently on Amazon Prime. The show originally straddled the 80s and 90s and focuses on a Starfleet in the 24th Century. It's an absolute blast and a brilliantly iconic part of Star Trek lore.

4. Stargate SG-1

Stream Now (Prime Video)

Given the struggle to bring the original 1994 Stargate movie to the screen, and its decent if unspectacular box office returns, it’s remarkable that it went on to spawn such an enduring collection of TV spin-offs. Stargate SG-1 remains the most prominent, running for over 200 episodes across ten consecutive seasons. One of the bosses of its parent studio, MGM, would describe the show as the television equivalent of James Bond to the studio, such was its financial success.

The personals column of 1990s sci-fi magazines stopped being about Girl Meets Boy, Boy Meets Girl, Girl Meets Girl and such like, in favour of Scully seeks Mulder, and plenty of variants on that. Such was the grenade conspiracy drama The X-Files threw into popular culture, instantly making stars of Gillian Anderson and David Duchovny. There was a spin-off series too, The Lone Gunmen, but that never fared anywhere near as well.

A massive budget Babylon 5 did not have, but a cauldron of ideas it absolutely did. And the similarities between it and the subsequent Star Trek: Deep Space Nine raised questions ultimately nobody tested in court. It also had a bold idea, to treat each of its 100+ episodes as a chapter of a novel, one that ultimately covered five years in the life of a five mile-long space station. In its own way, a groundbreaking show, whose first season boasted effects done on a computer many people had in their own homes.

7. The Mandalorian

View on Disney Plus now

The Mandalorian is old-school event television that's just a joy to watch. It's episodic with a new-ish adventure every week - the only real bit of connective tissue is The Child, a Yoda-like figure that The Mandalorian feels obliged to protect. Each episode looks (and is) expensive and it really feels like another area of the world of Star Wars that hasn't been explored yet, as well as some familiar bits too.

8. Star Trek: Deep Space Nine

Stream Now (Netflix)

By all means, substitute your own Star Trek variant here. But for the purposes of this piece, DS9 gets the nod. Deep Space Nine may not be the finest of the Star Trek television series – although it’s a fight many are prepared to have – but it’s the most quietly ambitious. Furthermore, it sees Star Trek go into more morally grey areas, with sometimes less obviously likeable characters. A turning point in one of the planet’s two longest-running sci-fi shows.

9. Doctor Who

Stream Now (Netflix)

Given Doctor Who has reinvented itself successfully many times over its near-60 year lifespan, it’s worth a venture into cliché corner to suggest the show, at some point, has had something for everyone. The incredibly successful 2005 reboot of the show, overseen by Russell T Davies, not only brought in a legion of fresh fans, but was all the more remarkable given that the programme had been near-dormant on screen for 16 years beforehand.

10. The Twilight Zone

View now at Amazon

Given the influences of The Twilight Zone on his movie Us, it’s little surprise filmmaker Jordan Peele is in charge of the latest reboot of the iconic TV series. The anthology show was created by Rod Serling and debuted in 1959, telling primarily sci-fi stories and attracting writers such as Richard Matheson (I Am Legend), Ray Bradbury (Fahrenheit 451) and in its later iteration, directors such as William Friedkin (The Exorcist) and Wes Craven (A Nightmare On Elm Street).

11. Westworld

Stream Now (Now TV)

True story: the low budget 1973 movie of Westworld, on which HBO’s hugely expensive television series is mainly based, introduced pixelisation effects to the big screen for the first time. The TV series expands heavily on the late Michael Crichton’s work, taking what was an 88 minute movie and turning it into a far deeper, broader series about a robot theme park starting to go out of control. HBO was rewarded with its best-ever ratings for a series launch.

12. Black Mirror

Stream Now (Netflix)

If the aim of all good science fiction is to take life and technology now, and reflect where it could head in the future, few do it to as chilling effect as Charlie Brooker’s Black Mirror. Brooker wove in things he learned from his zombie Big Brother drama Dead Set, with the approach of the classic anthology series The Twilight Zone. Technology is the thematic glue holding it all together. Robert Downey Jr was amongst the many soon hooked: he optioned the episode The Entire History Of You for a (thus far unmade) movie adaptation.

13. Blake’s 7

View now at Amazon

From the brain of Dalek’s creator Terry Nation, Blake’s 7 ran for 52 episodes between 1978 and 1981, and was a notable counterpoint to the lighter sci-fi coating pop culture at the time. You can see the very tight budget stretch before your eyes, but Blake 7 is a dark, compelling story of a bunch of rebels fighting against a tyrannical array of rulers. To its immense credit, Blake’s 7 also looks like a focus group has been nowhere near it.

14. The Leftovers

Buy now on Amazon Prime

The Leftovers isn't just one of the best sci-fi shows ever made, but one of the best shows made. Writers/creator Damon Lindelof took all the best mystery bits of Lost and made everything a little more adult. The premise is slight: a rapture-like event has made sections of the world's population disappear - we see what happens to the leftovers. It's just three seasons long but by the end, things are wrapped up perfectly in an awe-inspiring ambitious conclusion.

From the brilliant mind of James Garland (Ex Machina, Sunshine) comes Devs. This smart science-fiction show is all about secretive goings-on in a tech company in Silicon Valley. It's full of conspiracy, weird-tech and it looks damn good too.
