There are a good number of sci-fi TV shows, but have you ever wondered which is the best series? Here are our favorites!

Dark Matter is a worthwhile show if you like parallel world narratives. But, and this is a fairly big but, the dialogue is completely uninspired and the pace is far too slow. | © Sony Pictures Television
The Last of Us is a TV adaptation of one of the most influential games ever, and it doesn't veer far from the original script from the video game. Episode 3 in particular is outstanding, but sadly the show got progressively worse with each episode after that. | © HBO Entertainment
Colony is a gripping, interesting, and unique experience that's hard to stop watching. It uses the theme of Alien invasion to reflect on colonialism and corruption. But, neither the script or performances are too strong. | © Universal Content Productions
Rick and Morty is a fantastic-animated series that gets all the basics right: character development, story writing, and production values. We would have it higher in the list, but after the whole Roiland debacle... | © Williams Street Productions
From is a fantastic show in terms of visuals, acting, narrative, and directing. After the end of each episode, you will be left with so many questions that need to be answered, and that's what keeps you hooked. | © Metro-Goldwyn-Mayer Television
Severance is a very original and high-quality series with all sorts of moral and psychological dilemmas. Despite being hard to watch, the show is smart and relevant, and it also features a perfect finale. | © Red Hour Productions
Babylon 5 is one of a few sci-fi shows that is still worth revisiting long afterward. Apart from the beautiful spacecraft and well-done early CGI, the strength of the series is in its storytelling. | © Warner Bros. Television
Legion is a mind-blowing piece of cinematography that casually switches between horror, thriller, and romance genres. It is an entertaining, character-focused mess that I thoroughly enjoyed and would highly recommend. | © Marvel Studios
While speculations and hype make Loki somehow overrated, the show is still pretty awesome. The script is... poor, but the performances carry it past the finish line. | © Marvel Studios
12 Monkeys has all the elements to become one of the best sci-fi series. The film portrays Bruce Willis as a jaded, hopeless character, breaking away from his usual invincible hero roles, while delivering a powerful reflection on humanity's fears. | © Universal Studios
Westworld is a little "hate it or love it", but all viewers will agree it's at least intriguing and the cinematography is stunning. One cannot help but appreciate the skillful camera work, set design, and use of lighting and color. | © HBO Entertainment
The 100 seems like a teenage drama, but it is actually a fairly haunting sci-fi series about survival after a nuclear war. This show is far from perfect, but it is entertaining and worth watching, especially considering its surprising development and ending. | © Warner Bros. Television
Humans is the British equivalent of Westworld, so it is guaranteed to thrill. The ideas in the show are not groundbreaking, but it has great pacing and super believable character arcs. | © AMC Networks
Counterpart is a very good adult science-fiction drama with high production values and an acting masterclass from J.K. Simmons. It's almost suspicious how well the show imagined a post-pandemic life. | © Gilbert Films
Orphan Black is one of the best sci-fi shows, with a unique blend of engaging and original storylines combined with well-written relationships between characters. By the time you finish the first season, you'll realize the show is addictive. | © Temple Street Productions
The Twilight Zone is one of the most interesting TV series, full of messages that challenge society. It has stood the test of time and is worth a watch, especially for the pop culture references it inspired. | © Paramount Pictures
Fringe is one of the best sci-fi shows you can watch these days, and it's highly regarded for its blend of science fiction and drama. It's great to see the problem of the episode comment on an emotional crisis a character is going through. | © Warner Bros. Television
The Expanse is a criminally underrated show in the popular media. The science is accurate, and space combat scenes are sublime, accurate, and incredibly well done. | © Amazon Studios
Though some episodes are weaker, Black Mirror is one of the smartest shows ever produced. It has unforgettable moments of horror, suspense, drama, and technology. And the concepts are inspired. | © Banijay Entertainment
Futurama might be difficult to get into, but it's an amazing series written by hilarious people who happen to be geniuses. If you do get the clever jokes, it's one of the funniest shows you'll ever see. | © 20th Television
Battlestar Galactica is one of the greatest sci-fi shows with great drama, action, and well-developed characters. The series has gripping storytelling and innovative use of sci-fi tropes, combined with strong performances. | © NBCUniversal
The X-Files is a little dated, but it still holds up thanks to the thought-provoking scenarios that underpin each episode. And, of course, the chemistry between the iconic leads. | © 20th Television
The Doctor, our quintessentially British hero, has become a pop culture icon. And for good reason, this is a show that has delivered decade after decade. Now, if you haven't seen it before you should prepare yourself for a far more light-hearted show than others on the list, but it's nonetheless a banger. | © BBC
The original Star Trek show has spawned a half-century-long franchise thanks to the incredible trio of Kirk, Spock, and Bones. It's hit-and-miss, but more hits than misses. Simply iconic, and easily the most influential sci-fi show. | © Paramount Pictures
Stranger Things taps into nostalgia for the 80s and captures audiences of all ages because it's entertaining. It's what we expect from a collaboration of Stephen King and Steven Spielberg: it's creepy, tense, well-acted, and atmospheric. | © Netflix
