Another answerMugger recommended a book called "Beach Music." If a movie were ever made of it, I know I would compare the he** out of the movie to the superlative book.
I, for years, did the same thing to Kubrick's "The Shining." Whenever I stop comparing it to the book, I can see it is a great film. (But the made-for-TV mini-series of "The Shining" is, to me, a better film and more faithful to the novel. Woops! There I go again!)
