Posted this on a similar thread: "M*A*S*H" succeeded both as a movie and series better than the book.
I liked "Carrie" better than the book and it was certainly a good adaptation of a Stephen King novel.
There's another side of this adaptation business that many have touched on. Do we like or dislike the movie version because of fidelity to the book? For instance, the first two Harry Potter movies are slavishly detailed and follow the books as closely as possible within the limitations of time and budget. The third film definitely leaves a lot of stuff out. I happen to think the third one is better for having made choices and because it is better directed. The first two movies suffer from an abuse of "reaction shots" -- the faces of various characters reacting to situations.
