this be a terrific movie and plain and simple . it keep you think and guess at what be really go on and and in the end and all the hole close . that be unusual for any kind of play with time kind of film and and all those involve deserve credit for do it right . while the whole premise of the science involve have a deep flaw in it and it not the sort of flaw that preclude the suspension of disbelief . denzel washington and jim caviziel and adam goldberg give memorable performance . of course and there be no one good than tony scott when it come to tell a story with picture and and he as good here and if not good than in enemy of the state . positive because i finish my popcorn before i even notice it be run low .
