Any ongoing sci fi tv series hou would recommend?
is one of the best Science Fiction TV series every shown, the other three being the original "Star Trek"
, Babylon 5"
, and the "Stargate"
series. (Well, you can add in there "The Twilight Zone"
" with regards to anthology series.)
"The Expanse" is based on a series of novels and short stories written by James S. A. Corey (actually 2 authors) and actually follow the novels very faithfully. The first novel "Leviathan Wakes" was told in the show's 1st and first-part of the 2nd seasons. The start of the second novel, "Caliban's War", was adapted in the second-half of the 2nd season.
Both "Dark Matter"
are also very enjoyable, but are less *Science Fiction* science fiction series (not a criticism). They have both had 2 seasons and will be starting their 3rd ones in 2018.
These three shows have not done overall that well in the ratings. However what is allowing them to continue is that there are multiple productions companies involved in more than one nation, so overall the (dedicated) viewership makes production of them worthwhile.
There is also "Sense 8"
which just started its 2nd season, another excellent *Science Fiction* series. It's producers are The Wachowskis (of "The Matrix") and J. Michael Straczynski of "Babylon 5". (ASIDE: The Wachowskis are not longer "The Wachowskis Brothers" since both are now MTF women.)
"Sense 8" has both a gay male and a MTF transgender characters. It is somewhat stylized in telling its story, but that is because it is a difficult story to tell visually, as it is of the formation of a group mind. (This is *not* like Trek's Borg, which is a hive mind. A group mind is where a number of people share conscious, but retain their individual identities.) It is just starting its 2nd season now. Before that, there was a 1st season and a Christmas Special(!).
(I know a good deal about Science Fiction, Fantasy, and Horror in general and in detail. I have long been involved, directly and indirectly, in the various fan communities of these genres.)
