Now that season 5 of The Expanse is about halfway done, I have a few thoughts:
The show is more beautifully shot than ever. It seriously looks major motion-picture quality, in both the real and digital aspects. The overall quality of the writing and acting is good. However, overall it feels too busy to me, with a lot of switching/juggling plotlines that seems to mess with the pacing. They're not entirely to blame for this as book 5 splits all of the main characters into separate stories, but as a viewer I'd rather they spend more time with 2 or 3 of the stronger elements rather than having each one pushed forward by 10 minutes per episode. For instance, I think it would have worked amazingly to make one whole hour that was Amos' entire journey on Earth rather than getting it parcelled out in tiny bits.
Since season 4, one of the things that's worked the least for me are the places where they've added/padded material just to keep certain characters in the story. For example, Bobbie's whole Mars adventure fell kind of flat for me, as did Avasarala's re-election. While Bobbie's was sort of lifted from one of the novellas they both seemed like they were just put there to keep the actors on the payroll, as book 4 sidelines pretty much everyone except the core Roci crew. While there's less of this in season 5 (because the source material gives everyone more to do) I'm similarly underwhelmed with whatever they're doing with Drummer. Like some of the season 4 stuff, so far it really just feels like they're keeping the actor on screen/under contract in an already overcrowded story.
Finally, I wouldn't be fully honest if I didn't admit that knowing we're not getting books 7-9 brought to television has somewhat dimmed my enthusiasm for the show a bit. There's so much I would be looking forward to seeing that isn't going to materialize, which is a drag.
Amazon hasn't done anything wrong with the show under their run, per se, and they've definitely put a lot on money behind it, but I feel like for a variety of reasons the first three SyFy seasons packed a better punch. I guess we'll see what the back half brings.
