Scared me...
A lot of people don't like this movie here it seems. You have to suspend a certain amount of disbelief, but I found it very effective at ratcheting up the tension. It scared me. I thought it worked well. It wasn't perfect by any means, but it kept me interested and on edge.
I think people are being too picky by some of the complaints. Going on about the camera, how it couldn't have happened like that. I just enjoyed the effect of it being sucked up then falling down. This isn't a movie to take seriously for heaven's sake, it's supposed to creep you out and it did that for me. The main thing that took me out of the story was the girl screaming when she should have been quiet and the use of the flashlights. But obviously we wouldn't have a movie if we can't see what's happening.
Someone claimed here that this movie was filmed by 12 year olds. What an idiotic statement.
