I got this movie on a whim through netflix and was pleasantly surprised. I tend to not be interested in this type of movie aka suspense thriller. I am more of a cult and comedy fan but I enjoyed this movie so much! I couldn't walk away. It kept me wondering the whole time and then ending was perfect. It actually got into my emotions and toyed with them. I was very happy with a movie that was this satisfying the whole way through. Worth the watch even if you don't think you like this genre. Brilliant even and dane cook doesn't do too bad in a serious role either.
