As far as suspense horror goes it is amazing. The story reaches a human side from the beginning. The characters are very believable and acted superbly. Although categorised as "horror" it features quite a bit of drama and family dynamics / conflict over the base of horror. Viewed from the site of each character there is quite a bit of development of each personality throughout the movie. There is a build-up from happy, new to the darker, murky side of this horror. The development is very palatable. The situations leading to the climax is quite believable and frightening. By believable I mean the stories you always see on TV and read in the newspaper about situations that can be happening right next door to your house. This is where the story shines: this development of the main story, descending from family drama and suspense to outright horror. One of the better stories in this genre I've seen in a while. Not really the concentrated bump-in-the-night, outright horror, but extremely worth the watch!
