Doors slamming, footprints, other "paranormal" shenanigans... It was the worst movie I've seen in years. Did I have trouble sleeping? No. I slept like a fucking baby because I was so tired from watching the worst horror movie in recent history.
I don't know how anyone could enjoy it... unless you totally skipped out on Blair Witch. I guess it could be freaky if it was based on actual events or was an actual recording - but it's not. Just like Blair Witch, it PRETENDS to be real to scare the audience.
The problem with this is that it's already been done. Genius idea to whoever made it though, almost blatantly copy an idea that was good at the time (I remember it was about 10 years ago when I saw it, cause I was in 6th grade camp and everyone was freaked out to be in the woods) so it can appeal to the next generation.
Fuck this movie.
As a sidenote, the last movie I lost sleep over is noted in my blog. It wasn't as scary as it was disturbing, but I was also really high so I couldn't stop thinking about it. If you're scared of a shitty movie like Paranormal Activity you'll probably piss your pants watching it.
