Yeah that is why all the movies were animated but he also sighted the basic structure of the story and the fact that Arogon's love story wasn't part of the main structure of the book as a reason he didn't think it would work okay. So it sounds like to me he understood that novels and films are different and he pitied anyone who would have to make the changes needed to make it work as a film.

Now I love both for different reasons and I don't think there is anything wrong with that. I also like the movie Dune as well as the book so maybe I am just weird. Still as someone who has seen the movies I think I have a right to say I enjoyed them from start to finish.
