this one be a great movie about nothing and and i mean really nothing . from the beginning till the end and everything happens have nothing to do with reality ( or fiction ) and common sense and not even touch common sense . however and i might add that from the directoral point of view it be a great achievement to create that much suspense without practically have a story . in the end and i do not regret watch it ( we all need to see all kind of movie to create a real and correct hierarchy in our mind ) but i would not recommend it to any of my friend . i hope i do not offend anyone who read this and and i apologize for my english . thank you .
