I binged this over the past 2 months. It was an enjoyable watch and I'm looking forward to season 5, but I also don't think it's quite the masterpiece that most of you consider it to be. I understand why it draws comparisons to Game of Thrones, but GoT was in a different league IMO, at least until it fell apart in the later seasons. Just a lot more depth in GoT, much higher production quality, better acting across the board, etc. Minority opinion it would seem, but I overall like The Expanse or I wouldn't have gone through 4 seasons so quickly.
Season 4 was easily the weakest season for me so maybe that's why I'm a little underwhelmed at the moment. I was never a huge fan of Miller and I generally get annoyed when shows reincarnate dead characters, so to have the entire plot of season 4 based on Holden following Miller's every whim was an ongoing frustration for me. Holden/Miller got them into a huge clusterfuck and then got them out of the same clusterfuck, albeit with a bunch of people dying along the way, and that's somehow a win? Also got a bit bored with the election drama on Earth and I'd like to see Bobbie more involved in something meaningful.
According to those of you who read the books, season 4 was based on a weaker book, so hopefully things take off again in season 5.
