I really enjoyed this show overall, probably because it was just a decently produced sci-fi series (the bar is low)... But this show after season 3 just really took a step down. I was "fine" with the show after that, and enjoyed parts of it, but the first 3 seasons were legitimately great.
Did the source material just fall off a cliff after the proto-molecule stuff was resolved? That shit was far more interesting than the Belter shit. I'm sure this has been asked, can I read the books that take place after the series, or do I really need to read the first few. I have a hard time I missed THAT much from the earlier books.
