This movie is an emotion. One has to be with an unadulterated heart and open mind to get into and enjoy such emotion. If you are not suffering from an "all correcting judgemental superiority complex", and if you are not an intellectual loony toon, then you can definitely get that emotion and enjoy the movie.
I think some people are negatively criticizing this movie, probably because they miss their b grade item numbers that sell half nude dancers and, mindless & meaningless fight scenes.
