I heard Dan Simmons being interviewed on NPR about this. This guy is very talented. Most of his books are really good. He crosses genres with ease. In the interview, he opined that nobody was asking him how to do the adaptation and that he thought they were trying for too much detail and maybe missing the most important part of the story line. Its been a long time since I read those books.
