That the film ultimately reveals itself to be about redemption and the process of healing over hopelessly succumbing to evil also gives the proceedings an added layer of worth and freshness.
I really don't understand the purpose of this movie. Horror? Please, it's not a horror at all, it's just about two maniacs who want to take over identities of some random troubled family, for no reason and without any explanation except that they are crazy. There isn't even jump scares or gore, nothing that could classify this as any type of horror. It's just plain stupid, a waste of time. Stay away from this, people, not worth a minute of anyone's life.
