Five friends go to an out-of-the-way house to summon a ghost called The Butcher. Nobody thinks it's real, so they believe they'll have one or two days of just sitting back and trying not to laugh too hard as they conduct a ritual to summon the spirit. Unfortunately for them, the ghost turns out to be all too real. This is filmed through camcorders, as most of these found-footage films are, so don't expect anything out of the cinematography.
I have to disagree with one of the other reviewers who said it's the best found footage film since The Blair Witch Project. It was interesting, but kinda boring until the entity finally showed up. First of all, it was only 69 minutes long. When you have 5 characters in such a short film, it's hard to build enough of an attachment for the audience to care about them. That's what happened here. Plus, it's not as though a group of people looking for a ghost by using dark magic hasn't happened before in a movie, so it wasn't very original. And then the clichés of no cellphone service and the car not working happened. There were a few scenes of special effects, but it wasn't over-used, so I think they got that about right.
I gave this a 5-star rating, because the acting was pretty good, and the people conveyed a real sense of fear. However, I've seen better found-footage films. Still, it was entertaining enough for what it was. I'm glad it wasn't longer, because I couldn't take much more of the screaming and the jerky camera footage from the running. If you're a found-footage fan, I recommend this. However, if you have limited time to put into movies, I'd advice you keep looking.
