Ok, do not, I repeat DO NOT, watch this show while it's airing(releasing).

Binge the seasons, then ignore it till the next season is done.

The beginning of the seasons are TRULY abominable, like Jon Snow: "I DUH WANNIT" bad, or Michael Burnham season 2. Then midway suddenly the writing stops smelling its own farts and becomes decent, then actually good.

They just put SO much horrible, horrible, truly awful, it's not buildup, it's this nasty pretense to force the illusion of mystery at the beginning of the season, like they disorient you on purpose to seem smarter, but halfway through they stop and the whole thing becomes semi-coherent again.

As for the books, first: It's more than the standard trilogy, it takes so much from Asimov's extended universe, including where he joined his Caves of Steel series into the Foundation way later on, like the 80s.

There's definitely connections, but also, it's getting there by a different route, I don't hold this against them, you need room to create, just trying to make a near cult-scifi pulp book from the 50s into a show is silly.
