Huge disappointment - watched it with great expectations considering the team behind the movie. One star goes for the cinematography and some of the "inspired" camera work (the chase in the forest - if you know, you know). One more star for the acting because everyone did a great job acting their roles.
But, the screenplay and story were just... dead (no pun intended). Too much of unnecessary slow motion, stretched fight scenes that are edited pretty badly; this movie tries too hard and incorporates multiple styles of cinema and ends of being the worst kind of mixed rice bath.
The one song is good - but you might as well watch it on YouTube instead of the entire movie. It's really mindless and it's just a bunch of unfunny clips put together with an excuse to splash vividly fake blood everywhere.
