The trailer establishes disequilibrium and a sense of panic by not showing the villain's face clearly. It reinforces thriller conventions through the use of iconography like a bloody knife. Technical elements like low key lighting and fast editing are used to create fear and engage the audience. The narrative structure links to various theories around binaries, enigmas, character types, and disequilibrium to set up themes of good vs evil, innocence vs darkness, and whether the boy can escape the villain's control.
