Well, if you haven't looked into The Expanse yet, now would be a very good time. Next week is the season finale and a double episode at that, which will quite likely deliver, based on the series so far. So you can watch all the lead-up and then spend just a few days being excited
The B3D book club thread might have mentioned the source novels before (too lazy to check), so here's a short summary.
The setting is the near future (about 100-120 years beyond) where humanity has colonized most of the solar system. I don't recall the source of the quite but the tripod is supposed to be the most unstable political system - so obviously we have an overpopulated Earth under UN rule; Mars as an advanced militaristic power terraforming the planet; and the somewhat terroristic Outer Planet Allience growing among the the population of the asteroid belt, Jovian moons and minor planet Ceres and such. Also, tensions are of course at their highest. There's also a sub plot about space Mormons.
It's mostly a hard SF setting; there are fusion drives in the starships, but no artifical gravity and direct energy weapons or FTL communications. The first book - and thus the first season of the series - is an interesting and compelling mix of film noir detective story, political machinations, and sort of space opera (still grounded in the tech). There are quite a few interesting and compelling themes under all the running and shooting and exploration, too.
Opinions vary a bit about the novels' writing, but they're definitely page turners. Also, one of the writers works as an editor (?) for good old GRR Martin of Song of Ice and Fire / Game of Thrones fame. We're up to five novels and some complementary material; book 6 is due this summer and the plan is to go for 9 altogether. The writers are much better at delivering than Martin, too
The series are, IMHO, a pretty good adaptation. The authors are quite involved and they weren't afraid of rewriting and restructuring stuff for the show, and a lot of their choices are actually quite good. So pretty muc everything that made the novels good is present - they've even included a character only present from the second novel on, to add more perspective to the story and the themes. Most of the actors are at least OK, and they also have Thomas Jane as Detective Miller, with a silly hairdo and hat which still work. Production values are amazing for a TV show IMHO, lots of nice sets and wardrobe and really good CG; although I don't agree with a few design choices about a specific element. There's also a single issue that I can't complain about - the novels depict people born and raised in zero or low gravity as sort of really tall mutants with elongated thin limbs and large heads. Obviously this isn't feasible in a TV show and would be pretty damn hard even in a high budget movie.
I've seen the show called the best thing since the new Battlestar Galactica; but seeing the strong direction and execution in the later novels, I'd say it has the potential to become even better (the series are already renewed for a second season and I can't wait to see what they do with the next novels). So even if we'd already had a LOT of cool SF TV shows on air, I'd still say that this is really a must see
