Hmm... I wish I were more excited about this. Seeing a genuine hard-SF space show on TV is remarkable. I like the realistic approach to space and ships and physics, and there are some nifty touches like the bird on Ceres flapping its wings so infrequently -- although there are other annoying concessions to being filmed on Earth, like the silly trope of people using magnetic boots to walk around (which is enormously less efficient than just floating). And for once we get an explosion in space that doesn't look like a fiery liquid-fuel explosion in an atmosphere -- although they still cheated by making the nuclear blast endure far longer than it really would in vacuum. Without an atmosphere to heat to incandescence, the flash would be over in a split second.
The setting reminds me a lot of my own Only Superhuman -- the focus on an Asteroid Belt culture centered around Ceres, with Earth and Luna combined under the UN or equivalent and Mars as a separate sovereign nation. (Although I resisted the standard SF trope of treating "the Belters" -- or Striders, in my case -- as a single monolithic culture, instead making them a variety of competing subcultures.) So I wanted to like this.
But I'm afraid I don't find it very engaging. Too much of it is stuff we've seen many times before -- a society on the brink of war, ruthless corporations and wage slaves, corrupt cops, your typical dystopian stuff. Virtually no sympathetic characters; the only decent thing anyone did was Holden undeleting the distress call, and that was something he did reluctantly. So far, they haven't given me much reason to care about any of these characters. And the casting department did not do well on the diversity front.
