This show reminds me of Larry Niven's "Belter" stories, and his known space series of books which goes all the way back to stories of Gil "The Arm", who was a Belter who moved to earth and became a police officer for the "amalgamation of regional militia" aka ARM, Beowulf Schaeffer who had a relationship with puppeteers and flew a couple of their different general products ships, one of them into the center of the galaxy discovering that it had exploded. another to an antimatter planet (and apparently GP Hulls cannot tolerate Anti-Matter)- and his possible son Louis Wu via his GF Tanya Wu (See the book "Flatlander" by Niven) aka "Luweewu" who flew to the Ringworld and was last seen hanging out with the former "Hindmost" of the Puppeteers after saving the Ringworld from destruction, Protectors (3rd stage humans who become too smart and only are interested in preserving their own bloodline, so they always fight each other, killing everybody else in the process) and an ARM navy that was stupidly fighting each other with antimatter weapons around the orbit of the Ringworld.
But that is a huge universe created by a different author. This series of books and this show based upon those books, is restricted to our own solar system and the governments of Earth Mars and the Belt which does not really have a government.
And so we see a lot of things that also exist in the Larry Niven Known Space universe: including the mining of asteroids in the belt, or minerals and water, and the idea of Terra-forming Mars.
But one thing that is different about this universe is that so far, The descendants of mankind who have populated the solar system have not really encountered any possible alien life-until now.
And the concept of life that is thought up in this show is very different- in fact in 2 1/2 seasons, I still can't figure out the nature of that life form.
Thomas Jane is a Ceres cop, who is given the job of locating the daughter of a rich industrialist, Julie Mao (Father named Jules)- she is the centerpiece of the series for the first season and a half or so- even though she doesn't really appear or interact with any of the other characters other than in flashback sequences. In fact the entire first season is a search for her among other things. Thomas Jane is Joe Miller, the Ceres Cop, and has made finding her his obsession because maybe it's the one good thing that he's ever done and he becomes so absorbed in finding her it causes problems with some of the other people in this series.
Also there are quite a bit of politics in the show, sometimes directly relating to our own politics of this day, and a lot of this is extremely relevant.
We also have four people, Jim Holden, Alex Kamal, Naomi Nagata and Amos Burton, who through no fault of their own become the crew of a ship that they have named The Rocinante, they were all crew members a board a ship called The Canterbury, sent out on a rescue operation which also just so happened to involve Julie Mao...
And they become an important part of the story as well eventually Joe Miller gravitates toward them - and so does every other problem in the solar system it would seem.
Later, other crew members include a gunnery sergeant from Mars and a botanist from Ganymede- and maybe even his daughter, which she lost track of during a catastrophe on Ganymede.
I'm not sure if this show is going to continue into a fifth season, but if they can make a fifth season as interesting as the first three that I have seen, then I will definitely watch it.
There are a lot of actors that I don't recognize except for Tom Jane who was The Punisher, he is a little older now but he still looks great even with the beard, and Florence Faivre who was a very nasty piece of work Kree soldier in Agents of SHIELD, she's the one that had those two floating balls that killed people, eventually killed off by Quake in a most satisfying way...
Sometimes there are stupid decisions and arguments in some of these episodes which make me want to strangle the characters when I see it, but so far I like how things have worked out tween them, the crew of the "Roci" are friends, and this show depicts a very realistic friendship between these people. The small conflicts between each of them at the beginning of the show shows how people from all kinds of backgrounds could become good friends under the right circumstances.
There are all kinds of other things going on, on earth, on Mars, On Ships various places in the solar system, and especially at a base called Tycho where the Mormons are building an incredibly huge ship called The Navoo... that is just another problem.
