Another great question!
As far as movies based on books that I have disliked, I have to say that the movie of Memoirs of a Geisha was a huge disappointment. I love the book, and I was afraid the movie couldn't live up to my feelings for the book and sadly I was right. Oh well, maybe some day someone will remake it, or better yet make a mini-series out of it. In Japanese. I can dream! :)
