Agree. It is not the books, perfectly, and Asimov left so much out that any adaptation would need to fill in substantially. I think they’ve done great. Hope it serves to introduce Asimov to a wide audience.
I like that the second season can be free from having to set the scene and can focus more on the characters and plot movement. It feels a little faster. More things are happening in each episode.
I couldn't get through the first season. The Empire stuff was good, but I thought they really butchered Seldon. In the show, Seldon is portrayed as a warrior with a mystical connection to the vault. In the book, the whole point of Seldon is that he's a regular but smart person who leverages his opponents' beliefs in mysticism against them.
Season 2 has more seldon but is pretty awesome. You just have to let go of the books and let the show stand on its own otherwise some of the stuff will bother you especially until the shows additions changes and explanations make the thing that you saw seem reasonable.
