I actually think 3.5 because the perp's motivies are not really explained, other than the fact that he is crazy. And why is it that the girl has nothing that we wants people to see. Everyone has something they want people to see as well as something to hide. But I enjoyed the film on the second viewing. Very different approach. Good to great acting. Little too much nudity for my taste. Used like car chases when the story gets weak.
