I'm starting to enjoy Miller's arc a lot more. I wasn't really fond of his side of things at first with all the action happening with James and Naomi, but now that I got my dick wet I can start appreciating the politics and subtleties of belter life. I'm curious how Julie Mao fits into all the chaos especially with the OPA and the mysterious 4th party that arrived in Episode 4. The Fred Johnson flashbacks were really interesting too. I've really been itching to read the books and I might start the first book once the first season is over just so my mental image of the characters will match up.
Also, I think it's a little strange that we're not seeing Avasarala's side of things in this episode but my understanding is that a lot of stuff that happens from her point of view is in the second book so I guess that's fine. I don't suppose she really needs to play a part with the Cant and Ceres station shit since they already figured out that it isn't Mars that's trying to provoke a war.
At this point i'm really happy with the show. It's still going to get compared to Battlestar Galatica since it's really Syfy's only other critical hit, but I have come to terms that it's not going to be the second coming of BSG in terms of themes and characters. The more I separate the Expanse from BSG the more I start to enjoy it.
It's really tough to not buy the entire Expanse book series right now.
