This could have been a nice little gem of a movie. Good atmosphere and tension, some good horror here. But key fatal flaw ruined the movie for me. Minor general spoiler: It's annoying that the attacker is incapacitated on numerous occasions, but each time the boy immediately runs away. Does not bother to disarm, fully incapacitate, etc. Of course attacker got up each time. Is this the best the writers can come up with? After perhaps the 5th time this happens I kind of lost interest and it became silly.
