- How quickly the father goes from apparently good-natured family man to psychotic religious zealot. One scene he's enjoying a peaceful dinner with his kids and offering to help one of them out with their homework, and then mere minutes later we get a scene of him barging into their room in the middle of the night to inform them that he received a vision from God telling him that many everyday people are actually demons in disguise and it is his duty to "destroy" them. At no point does he ever even entertain the possibility that this is ludicrous. It's truly unnerving to consider that people this deluded really do exist in the world.
- There's also the fact that Adam buys into this "mission" just as easily as his father. Such a sweet young boy, and yet so easily corruptible.
- The murders are absolutely this, with some well-executed Gory Discretion Shots that make sure to leave just enough to your imagination.
- Fenton being locked in a cellar for over a week, and only being let out when he claims to have seen God.
- The Reveal near the end that the father was right all along and all the people that were killed (Fenton included) really were demons. It places the entire world of the movie into borderline Crapsack World territory.
- Continuing with the Crapsack World theme, law enforcement seems to be utterly filled with corruption and incompetence. The sheriff from the flashback refuses to take an accusation of murder seriously, the FBI agent in the Framing Device is a murderer, another local sheriff is a Serial-Killer Killer, and even said sheriff's secretary seems to be in cahoots with him.
