well, at first sign it seems a very interesting movie. The story stars good, the gore is good even the actors are good. But there are a lot of problems, first of all the ending is too obvious, you can figure out really fast. Then the gore scenes are ridiculous, i mean how can a person cut off their fingers without make any expression and there is another scene when a girl is falling from the ceiling and the body explodes like a blood bomb!, those moments are very stupid that doesn't shock you that makes you laugh.Just before the end, the movie turns somehow into a musical, the good story turns senseless, stupid, obvious. i really don't recommend to buy this movie but is worth see it, at least you learn something about japanese cuulture.
