My favorite one was "The Sixth Sense" not just because of the great ghost story/horror flick, but because of the very sad love story that was happening. I cried like a baby at the end of that movie, and have with each repeat watching. Just sad.
I do have to say that I enjoyed "Unbreakable" and "The Village"..both very entertaining. Haven't seen them in a while, but from what I can remember, I enjoyed.
