I have to agree with pdr: the main idea behind the movie only works if you have doubts yourself... the way it is presented definitely not!
When this first came up I dismissed the movie as a crappy hollywood slasher because it looked rather dumb. Only just recently I was made aware of the fact that it's the same director as the french movie Martyrs so I was intrigued. The whole marketing for this movie is so misleading it's not even funny. In my case it did it even more harm than good. It's not the worst movie I've seen but I expected better. Props for him trying such an off-kilter concept, unfortunately it was too underdeveloped.
Movie message is not clear, too presumptuous. Movie is basically bad.
Great movie. Loved it. Not the movie I expected and I was pleasantly suprised.
I like the atmosphere of the village at the beginning and the movie starts nice.
However, I don't buy it when suddenly all villagers are "evil" this is too much and stopped watching. Didn't like it, watch Jack Reacher it's better ;)
