Went and saw it last night, thought it was great. Awesome movie, horrible ending though. It currently has an 8.0 rating on imdb.com. It creeped me out a lot, like it sent chills down my spine at least 10+ times. I'd say it only got corny once. It's worth the money!
John Cusack is an author who gets drunk and destroys a hotel room. It was fun! haha
