As said by one of the reviewers below, the show has little to do with the novels. It does not emphasize the psychohistory and the relationship between the characters seems nonsensical to me, although the gender updates are welcome.
The tv show presents some drama that is not apparent in the books, and a lot of time is wasted on the boring dialogues.
The vault also barely relates to the one described by Asimov.
I ended up frustrated with the tv adaptation, and most likely, I will not watch the second season.
