For me I can watch this movie unlimited times. This movie is not a movie but a very very very deep roots of human psychology as seen in poster. Its my one of the fav movie. The last second of the movie is incredible shocking .
Just one second of the movie that scene . That makes our mind say OMG what was that and movie ends. Its for those who love deep mystery movies not for entertainment. Its a masterpiece that can be watch many times still you will find something new in it.
