I first watched the trailer of this movie, which made me really excited to watch it. Add to that, that it stars Jay Chou, who I really liked(as an actor) after watching the Green Hornet. Unfortunately, the movie didn't live up to my unreasonable hype. The story was alright, though it felt like they were trying to cram in too many things into it...including time travel. The acting was better. The music was relatively mediocre. As for rewatch value, im not a person who rewatches most things, but for this i'd say don't rewatch it. Overall, i'd give this a 6. I guess it's alright for a Saturday night where you have nothing better to do or if you're a fan of Jay Chou.
