Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed.
Question: In the very last scene, we see Michael Shannon in shackles (presumably in a federal prison) with electroencephalographic sensors attached to his forehead and scalp, oddly gazing at the sunrise as two prison guards flank him. In the very last shot of the film, a closeup of his face, we see his eyes faintly glow for a split-second as he smiles a very slight smile. Question: Is the film implying that Alton is in otherworldly contact with his father, or that his father absorbed some of Alton's otherworldly power; or is it implying that, being the boy's biological father, he was the source of Alton's power? In any event, this may never be revealed, because the film barely made back one-third of its $18 million production budget, making the probability of a sequel highly unlikely.Charles Austin Miller
