I honestly don’t see why people hate book-movies when they aren’t 100% accurate. I mean, I would prefer that a directly based film should be as accurate as possible, but not everything in a book can be properly portrayed in film, and if someone wants to adapt it then they’ll have to accommodate. Then you have adaptations that are only loosely based and aren’t supposed to be connected to the source material very much. When a film isn’t as good as the original book, I just read the book. Think of MASH. I think the book is a lot better than the film, but there are certain things that the film brings with it that make it a comparably enjoyable experience.

EDIT: I really need to stop making such long posts.
