Well,

Rating: 8/10 (13 April 2007)

I actually enjoyed it. I went with friends and was in a large, sold-out theater, which added to the experience.
This is the first thriller/horror movie I've seen in recent years that I actually sat through. The plot, although fairly predictable, was more than enough to entertain. The story sets itself up very nicely, and continues throughout. There are multiple moments that made me jump a little bit, and the main sequence definitely managed to get my heart racing. Also, I felt that the actors, particularly the younger ones, did a very good job. A problem with horror movies I tend to have is over-acting, but, in this realistic plot, the characters tended to react as such.
There were a few points to bring it down, however. The plot and a few of the "get-you-to-jump" moments were altogether too predictable (although this is admittedly hard to avoid, as you're expecting to jump. It's a suspense movie).
In conclusion, it really was a good, thrilling experience. There were enough unexpected turns in order to maintain the experience. I especially recommend this film to teens, as most in the theater were very pleased with the experience.
