This movie really surprised me. I was expecting another lame cheap slasher film, and instead this film is smart, funny, and really well-acted. The plot is like Groundhog Day, except this has a college sorority girl who is self-centered and mean reliving her death on her birthday. She cleverly wakes up every day closer to finding out who her killer is, but gets weaker in the process. The twist ending really twists more than once, so just when you think you have it figured out for you, you are totally wrong. Again, this movie is smart, funny, and well worth your time.
