Saw this a few months back (DVD already out in States), was very disappointed by this film. To me it felt very unbalanced, one moment it was a serious comment about teenagers virginity and another a dumb comedy. The main female character changed more than someone in Eastenders.
My impression of the film was that it was just "ok", though I was expecting something maybe more serious I would have been happy if it was just some chick biting guys cocks off with her fanny teeth but it just wasn't entertaining enough.
