I understand the of the many pseudo intellectual explanations of this film and it's metaphors. The characters and their interactions when they are stuck in the house together are the only worthwhile reasons for watching. Just wanting Mallory and the children to survive, is the only reason why I got to the end although not even that is not believable. The problem with films like this is, that if you do not believe in unseen things like the supernatural or religion, it just is not scary or believable and is quite laughable at times. Please bring back the old suspense thrillers which were full of things which could happen.
