The Expanse is pretty good. I'd recommend both the books and show if you're into science fiction at all. It's a fairly hard (when compared to your typical hollywood scifi) take on a colonised system and a cold war between Earth, Mars and the populations of the Asteroid Belt. It has some weird stuff like stupidly efficient drives and no radiators but ships have to do deceleration burns, there's no lasers or plasma weapons and gravity is provided by centrifugal force or thrust of engines. It also does a really nice job of fleshing out the cultures of Mars and the Belt based on the conditions they live in, and makes the world feel very believable.The first couple episodes of the show are a little slow to start off because they're mostly just worldbuilding stuff to get the viewers caught up with how everything works,so I'd say that if you're not interested by episode 4 then chances are you won't be interested in everything after (personally, I was hooked more or less based on how good the opening titles were because they just "felt" something unique), but otherwise I think it's the best space scifi we've had on TV since the early 2000s. The production value is really nice too, the CGI and sets look pretty great for the most part, and they only get better as it goes on.
