I'll concur with the people saying that seasons 2-3 was probably the peak? Season 1, especially early on, was just a bit rough. Season 4 was a story that didn't translate well to TV, IMO.

Season 5 was cool, but if I had a complaint about it it was that maybe it needed to differ a bit more from the book, a big part of this book was that it was the first time you ever learned anything about the Roci crew's backstory besides Holden. The TV version was probably right to reveal some of that earlier, but they probably needed to change up season 5 a bit more to compensate for it because some of the stories ended up feeling like a bit of a drag.
