The document summarizes how the media product followed conventions of psychological thrillers in its opening sequence, such as showing a hand under the bed. It also challenges some conventions, like revealing the murderer early. The sequence establishes an antagonist (the murderer), protagonist (man at the door), and enigma (who was killed). Mise-en-scene and soundtrack were used to further conventions. The setting in a sparsely populated area challenges conventions by creating a sense of isolation.
