I know this is a long forgotten thread, but doing a scour of the forum, I thought I had to put my two cents worth (and maybe stir up some new discussion).
Now, "Adam Sandler" and "good film" are usually two mutually exclusive expressions. However, I've always loved Punch Drunk Love - except for the ending. It's all leading up to this confrontation between Sandler's character and Philip Seymour Hoffman's character - and then it's all over way too quickly. It didn't quite seem resolved in the best filmic tradition. Any thoughts?
One thing I must comment on is how Kubrick showed great taste in not going with the ending Anthony Burgess had in the novel of Clockwork Orange. Kubrick ended the film with the penultimate chapter of the book. My edition of the book actually ended with Kubrick's ending. It was ages before I saw an edition that showed the extra chapter. That extra chapter would have (in my opinion) negated every point the film had been trying to make.
