Have you ever read a book after watching the movie/television version only to find that you don’t like the book as much as the adaptation?
I can't think of one movie I've watched first and than watched the movie version. If I know a movie is based on a book, I always read the book before viewing the movie. The books are always much better than the movies, in my opinion. However, I am sure I've watched many movies based on books, I just didn't know it at the time. Aren't most movies based on a book? I don't know.
