This film is so underrated, the hate it gets is undeserved.I can agree the movie is no where near as scary as you would expect for a horror and the middle of the film does start to make you wonder if its actually a horror movie or not. However, i was still entertained throughout the whole movie which all eventually built up to the ending, which in my opinion was amazing. It was so unexpected and really made up for the slow build up of the story. The reason i am giving this film 4 stars instead of 5 is because its supposed to be a horror and personally i wouldn't say this film fits in perfectly with any genre but i would probably have chosen thriller instead of horror. This is definitely worth a watch if your looking for a good psychological movie.
