I enjoyed The Expanse. It's split into two primary storylines -- one featuring a space crew, and one a kind of noir-ish detective (played by Thomas Jane). In my opinion, the space crew storyline isn't that compelling (due to the writing and acting) but the other storyline is great. The entire show is way more scientifically accurate than other sci-fi shows, but it isn't geeky about it. It still puts characters first. I also enjoy the ambassador character, who is kind of Machiavellian but not evil.
That's the first season anyway. I hear the second is better, but I've only watched a few episodes so far.
