This movie makes "The Hole" (3-D) look like "Citizen Kane". What am I trying to say? That for adults this will probably not work at all. While the mixture of the Hole (targeting adults and kids in a Horror movie) might not have worked all the time, it did achieve something. The movie right here has a lot of flaws, some of them being the giant holes in the story itself.
In Horror movies we are used to characters doing irrational things, but the movie almost seems to have the goal of topping even the most ridiculous of your expectations. What I really liked was the very moody beginning. And I guess if you are in the right age and/or not familiar with Horror movies, this might actually scare you a little. But if that doesn't apply to you, I suggest you use your time for something more satisfying.
