didn not see this in the theater and but a coworker tell me about it . wind up buy it on dvd and watch it with my girlfriend and buddy . one of the best movie of it kind . the plot be very good and and flow well . the action be believable . many question undoubtedly and but we have not be able to prove what an actual time shift act would result in . definitely a movie to keep you on the edge of your seat and and when the timeline converge at the end and it be a total surprise and bring the end in just like a story should . very few other movie top this . and i be eager for this writer to write something else with this kind of creativity .
