I get so tired of movies that put in the twist ending just to have a twist ending. Inception was not one of those. The Shutter Island twist ending did bother me because I knew it before I saw the movie with the 'who is prisoner whatever number' and that ending was supposed to be a surprise.

I think a lot of people lately think movies aren't as good if they are able to wrap up the story. Sometimes a movie is just a movie and it can end there.
