Some nice, smooth, consistent quality. Better Call Saul was in my opinion pretty consistent. Single season anime is almost always consistent, like My Dress-Up Darling or Terror in Resonance.
Not dragging on longer than the series needs to seems to be a key point.
True, and the same applies to the book that was adapted into that particular season. Cibola Burn is by far the weakest book, but then it’s followed by Nemesis Games, which is by far the best one. I do think, however, that The Expanse starts off very slow, and it only picks up the pace after the Donnager, three or four episodes in.
