Keenu Reaves is a good actor but certainly this wasnt the type of role he normally used to opt for. Having certain expertise and skill set in acting, he didnt fit well in the character unluckily. While watching the movie, you ll find those spoiled brat girls all up on your nerves since they extra-ordinarily did justice with their bitchy roles.
I found the movie very disturbing which was surely the director's intention which make it a good movie though- however the only discrepancy lies in Keanu's acting , which could be filled with an alternative replacement.
