a fine movie and but lack in story . a puzzle box movie and similar to rather butterfly effect than memento . mostly it turn you on in the beginning and slide through the story and keep you think when start the thrill . some good moment similar to the butterfly effect . sarah polley remind me her next movie my life without me all the time . it a pity . ryan philippe though have his best presentation yet . still worth a look . liked character and and it have some style . not all the answer will be answer and but still most of the point it lose be due to the end .
