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.

Oh yeah, there'd be some pretty good space fight set pieces. But trying to visually conceptualize all the Proto-molecule Builders and "Whatever the fuck extra dimensional critters they pissed off" probably would have been too difficult to do in a way to make everybody happy.
Also, what was it... like a 30 year time jump for the last chunk of books? That would have been a miserable thing to put all the main cast through for another 3~5 seasons.
It was a 10 year time jump so here's hoping we get a reboot in a few years and also it was cancelled because the guy that played Alex the pilot turned out to be a sex pest.
Nevermind you're right it was a 30 year time jump I just accepted it as the sort of future tech they had could explain away the fact Holden and friends would all be old and decrepit by that time in universe.
