I loved this movie. The development of the characters as the movie progesses was expertly done, in my opinion. I have told several people about this movie and actually saw it twice in the same week. I don't recall ever seeing a movies twice at the theater. I think everyone should see it.
This movie was terrible... very gory, very disturbing, and really not much of a plot at all. I didn't even care about the characters..very weak. I wouldn't even recommend it as a rental. In my opinion, M. Night peaked with his first movie and has gone downhill since.
