I like the movie not because it's horror, I think this is not a horror movie. It's mystery, you have to think either real or not (I know it is cliche, but some people love this type of movie). Although the beginning is too slow, but the ending got my attention. All strange things occur in the mansion (like the strange caller, the tongue etc) look realistic and logic at the end. Unfortunately, the beginning, as i said before, is too slow and lack of development. This is just my opinion, you have to watch yourself to feel the real experience.
