I'm going to keep this simple: This is NOT a good movie.
I'm not going to put any spoilers in here, because everyone else kinda did that. I'm not going to explain the characters or the story line, because others have done it, and there isn't really much to explain. But here's my take on it:
The story is bad, the camera work looks like someone shot it with an iPhone, the script seems like it's mostly ad lib, there is next to no gore at all (at least for a movie this bad, you would think that it would be heavy on the gore), the acting is HORRID, the characters are vastly underdeveloped, the interactions make no sense, the movie itself drags for the first half hour, and then when it picks up it is almost comical, there is NOTHING believable about this film--it's just a flat out mess.
I didn't give this a 1 because I've seen a LOT of bad movies in my day, especially of the horror genre. However, this movie didn't get a 1 out out of 10 simply because I've seen worse movies to compare it to, not because it wasn't really bad.
Read the other reviews, and compile them all into one. Everyone is telling the truth all at the same time, trust me. If you like rustic independent films shot by film students, then this is right up your alley. If for some reason you want to see a really good horror film, either just because you like horror films or because you want to kick Halloween off with a bang, don't waste your time.
