Maybe you gotta be into the books. They did a good job according to the book lovers, which is rare. A lot of stuff had to be left out but they absolutely nailed the look and feel. Also, the stayed extremely close to the story as written.
I get the feeling you would like the books. The author builds the world by explaining all the "macro". It's not too late either. The two movies cover just the first book out of like seven. "God Emperor " is my favorite, it's the fourth one.
