The plot is simple, a group of students conduct an experiment in a haunted house but things go awry and people start dying. In fact, I was ready to give the benefit of the doubt to this movie knowing the premise would not be original, however this movie lacks any real scare. The camera shots and camera angles were the best thing in the movie because it makes you want to strain your neck to see if there is anything hidden in the corner. Apart from that, there is nothing good that should be expected from a Korean horror. No emotional investment in the characters, no shock or scares. The acting was just decent enough but the main problem with this movie is that it does not really know what kind of movie it wants to make: an exorcism gone wrong? mystery thriller? or drama? This really ruins the movie and leaves you feeling cheated after leaving the theater.
