1. Battlestar Galactica (2004-2009)
The 2004 reinvention of Battlestar Galactica is generally considered to be a template of a sci-fi TV series because of the combination of space battles, political intrigue, and human drama. The show investigates the existence of man in the face of an unforgiving Cylon invasion, and it has intricate characters who are faced with ethical challenges at all costs.
The second viewing of this show allows one to notice small innuendoes, preludes, and ethical undertones that are difficult to see upon the initial viewing. The story of each episode is carried on by the relationships between characters and the political tension that intensifies with each consecutive viewing as a subsequent plunge into the universe richly created in the series.
2. Doctor Who (1963-present)

It is hard to find a sci-fi TV series as long and varied as Doctor Who. Over decades, time-travelling adventures in the show allow the audience to explore other times, planets, and versions of the Doctor. The episodic format, combined with the repetition of themes and character development, makes it very rewatchable.
A re-viewing of Doctor Who can point to the presence of intelligent foreshadowing, detailed plot interconnections, and subtle character development that might not have been apparent at first. Every Doctor has a new twist, and therefore, the show never gets stale due to the new outlook of the Doctor.
3. Stranger Things (2016-present)

Stranger Things is a unique contemporary sci-fi TV series, featuring elements of 1980s nostalgia, supernatural thriller, and emotional dramaturgy. The show is based on the Upside Down, a parallel universe where horrifying creatures exist and a world of mystery, friendship, and secrets of the town.

4. The Expanse (2015-2022)
Considered to be scientifically perfect and portraying the space and politics between the planets in the future, The Expanse is one of the outstanding examples of sci-fi TV series that should be watched by people who enjoy perceiving the world in the smallest detail. The show is based on a complicated process of politics involving Earth, Mars, and the Belt, as it discovers a mysterious alien technology that endangers humanity.
The rewatching of The Expanse enables one to notice the nuances of motivation of the characters, the dynamics of the faction, and technological details that enrich the story. Its extended plot lines are worth paying attention to, and the rewarding effect of each viewing is a more in-depth and consumable experience.
5. Black Mirror (2011-present)
Every season of Black Mirror offers an independent plot with the problem of the dark nature of technology and its effects on society. The anthology format allows one to rewatch popular episodes or even binge-watch the show. The sci-fi TV series in science fiction, such as Black Mirror, is unique in that it typically has some form of foreshadowing, hidden meanings, and deep ethical issues that can become more evident in the second or third watch.
The show is thought-provoking and endlessly engaging as it offers a new revelation on the implications of the near-future scenarios that the show depicts with each re-watch.
The five sci-fi TV shows are ideal to watch when one wants to rewatch extended plots, intricate characters, and discover deeper storylines. It can be the rough survival politics of Battlestar Galactica, the adorable escapades of Doctor Who, the nostalgic thrill of Stranger Things, the intricate world-building of The Expanse, or the philosophical musings of Black Mirror; there is always another reason to roll the dice in the second play.
There is more to re-watching these sci-fi television series than remembering old times, as they can also be looked at with a different perspective and the skillfulness that makes them so remarkable in their genre.
