I'm with SeanValen on this, I thought it was one of the best horror films in a while.
It may have some cliched moments, but I was really impressed and surprised.
Blows Insidious out of the water, the mood and atmosphere was tense and creepy from the start, the music was crazy, but really made a huge impact.
Some insane scares and extremely disturbing imagery.
Everyone at least give this a chance, go see it.
