Hide and Seek, cable fodder with Robert de Niro, isn't great but has a nifty twist that turns the movie inside out. It's better than The Sixth Sense's twist because there is no supernatural element.
Prior to the twist it is a movie about a father coping with his daughter's autism. After the twist it is about a daughter coping with her father's alcoholism. I stopped watching after the twist but appreciated that the plot dealt with real world social problems and not emanations from the spirit world.
