Usually when a book is made into a film, it usually just leaves me very unsatisfied. I myself prefer the book over the movies. If I do go and see a film adaptation of a book, I try and read the book or books first if I can. Usually with movies, even though they're only an hour to two hours long, they leave a lot of stuff out or change something altogether. The only film version that I'm aware of that stays true to the book is 'To Kill a Mockingbird'.
