I though there was a possibility that this movie would be interesting, and for a time it was, then it just got stupid. As each of the friends are killed the movie does create suspense, but it doesn't really explain why each of these friends of Laura are being killed, since only one of them posted the video. The death scenes themselves are pretty good, one woman you don't even see how she really dies, but you hear the police and see her body fall to the ground. It isn't your everyday horror film. It doesn't rely on gore to scare, it is more psychological, but at the end it loses something. It become a little dull. Even with the little twist at the end I lost interest and found myself losing scenes. For at least one of the characters I am not sure how they died.
Now, that being said, I'd say watch this. Like I said, it was different than most horror movies. It didn't rely too heavily on gore, and while it wasn't a camera style it was an interesting video style. I enjoyed that it didn't do too much with handheld first person videos or found footage. So while I didn't think it was great, I didn't totally hate it either.
