This is not a horror movie for those looking for traditional scares. This is a horror movie for those who have become accustomed to the sight of a specter in a mirror or a zombie just around the corner. This is a horror movie with a killer of no less eccentricity than a vampire or a werewolf, only the killer in this film blends in. He’s a next-door neighbor or a familiar face at the neighborhood grocer’s. He’s one of us. And when he’s explored he’s not shown as some unholy or supernatural freak. He is, just like the title, a maniac.
