I'm really mixed about this movie. I liked the movie/story up until the end. The twist wasn't bad as much as it was completely obvious and predictable from the start. You knew from the opening scene what the twist was going to be. I thought that the movie was well cast, although, at times, Sigourney Weaver looked like she was reading off a cue card with no emotion. All told, this is one of Shyamalan's salvageable films (especially when you consider how horrible The Happening is) but not his best.
