Not sure how I feel about this one. The first half of the movie was pretty boring actually. For an hour or so, the movie is kinda slow, and not that interesting. However, the second half does help this movie. It's an obvious message, how "normal" people turn into slashers and lose their compass.
I wish the first half was better, instead, we get a good idea, with a poor beginning. None of our characters have any depth, or a reason to really care, all are there for the sake of being there, and all struggle with the same problem: Women. I am curious how are the sequels to this. There are way better Asian extreme films out there like one of my favorite films The Untold Story or another film I dearly love Sweet Whip, or I Saw The Devil, all the films I just listed have a way more interesting plot, with loveable, characters, here you cant to that. None of our head characters are that likable, nor do they are interesting enough.
To summarize this movie, it's an Asian version of Hostel pretty much. The first half was pretty low, second half helps this movie a lot to stand on its feet. If you were a fan of Naked Blood or the Guinea Pig films, you most likely will enjoy this. To me, it was sort of okay.
