List Rules Sci-fi TV shows and series with science fiction elements

Here is a list of the best sci-fi shows and best sci-fi series of all time, as ranked by hundreds of Ranker voters. This list includes long-running sci-fi TV shows like Doctor Who as well as some of the best canceled shows of the genre. Science fiction TV shows have been around for decades, and some of the longest running shows have fallen into this category. Popular shows such as Star Trek have enjoyed several incarnations, and fan-favorite shows like Firefly and The X-Files have made the crossover from TV to the big screen.

Thanks to networks like SyFy, FX, and The CW, new sci-fi TV shows premiere every year. Sci-fi series like The Expanse, Orphan Black, and The 100 continue to raise viewership ratings and grow fan bases. Netflix has also contributed to the science fiction genre with their original series Stranger Things, which was met with rave reviews. 

Vote for your favorite science fiction shows to move them to the top of the list, or press re-rank to create your own list of your favorite science fiction series. Be sure to stop by to vote on the best British sitcoms and best current TV shows airing right now.

Almost Human is listed (or ranked) 84 on the list The Best Sci Fi Television Series of All Time
TerrenceMann added Almost Human Karl Urban, Michael Ealy, Minka Kelly In 2048, the uncontrollable evolution of science and technology has caused crime rates to rise an astounding 400%. To combat this the overwhelmed police force has implemented a new policy: every human police officer is paired up with a lifelike combat-model android.
 John Kennex (Karl Urban), a troubled detective, has a reason to hate these new robot partners. Almost two years previously, Kennex and his squad were raiding the hideout of a violent gang known as the Insyndicate, but ended up being ambushed and outgunned. Kennex tried to save his badly injured partner, but the accompanying android officer abandoned them both because their chances of survival were low. An explosion then took out Kennex's leg and killed his partner.
 After waking up from a 17-month coma, Kennex has to deal with a cybernetic prosthetic leg and huge gaps in his memory, which he tries to recover through visits to a Recollectionist in the city slums. Besides trying to remember as much as he can about the raid and the Insyndicate, he is also coming to terms with being abandoned by his girlfriend Anna.
 Kennex is then recalled to the force by Captain Sandra Maldonado (Lili Taylor), and partnered with a standard-issue MX-43 android, which he promptly throws from a moving vehicle because it was a nuisance to him. He is assigned a replacement android, an older DRN model originally destined for the scrap heap. Created to be as close to human as possible, the DRN androids have trouble dealing with some emotional responses, which was the reason they were replaced by the logic-based MX units. Kennex's unit, known as Dorian (Michael Ealy), immediately proves himself unique, with a clear dislike of being referred to as a synthetic.
