an interesting concept with some very cool idea that never really reach it potential . instead of explore the implication of time travel and the film sidetrack into a very rushed and hasty romance and one that never really make sense . the scene in the mental hospital add nothing new to the stock stereotype and and the end be telegraph a mile away . there be a few interesting idea on time travel that be bandy about and but they ultimately go nowhere and and the military scene at the begin seem to serve no purpose for the rest of the movie . the story be flaw and but it still interest and the performance be great and and the visuals be kinda cool but nothing outstanding . an interesting concept turn into a decent film . the thing that bother me most be the entire point of knightley character jackie . at first i just think she would be a sign to jack that he time travel and but then she end up help him and be the love interest . how would that happen . there a rather large leap from her throw him out of her place to her go out of her way to help him . it felt like there be a scene miss . in fact and all the scene in the future seem to ignore continuity and logic altogether . it be a bit disjointed and even for a sci fi movie . the idea bring up by this movie on time travel have be discuss much well in other film and work of literature and so the film doesn not add much more to it . the movie a decent watch and never cause you to lose interest and and the pace be perfect for this kind of film . it just doesn not seem to add up to anything special . it actually could have use a bunch more depth to it and to fill out the character and inject some emotion and realism into the film . still and it an interesting movie and at the very least .
