The main character in the opening sequence is a stalker, chosen because he builds tension throughout. The social groups targeted are teens and young adults of any class, gender, or sex. The film depicts a man seeking revenge after being bullied by a woman as a youth, showing male dominance. A frame showing half the faces of the stalker and another character builds tension, as the stalker's intentions are unclear, and a shot of him alone indicates this is personal and he is up to something that increases fear about what he will do.
