I've read the books and watched the show as far as it's aired. I agree, but I almost think it's good that Asimov's vision is getting smoothed out a bit. After "second foundation" in the book series, the books go in a very different, unscientific "woo" direction. The end of the entire series is bizarre and controversial. I'm not all that convinced I want the original ending to be preserved - it wasn't that good anyway…
It's literally about three people's journey across the cosmos to discover the origin of humanity and really, very little of the original story re: Seldon comes into it. It makes me wonder what happens in between.
