Awesome slasher movie!
14 May 2001 | by (United States) – See all my reviews

This movie is completely brilliant! Jennifer Love Hewitt, Sarah Michelle Gellar, Freddie Prinze Jr., and Ryan Phillipe are great in this movie! It did have it's share of blood and gore, but it was very enjoyable! I highly reccomend this movie! If I had to grade it, I'd give it a A+!
