The document discusses how the film opening adheres to and challenges conventions of the horror/thriller genre. It establishes mystery and ambiguity through minimal narrative, unsettled shots and clues placed in the mise-en-scene. Tension is built through slow initial shots and quicker cuts at the end. Common techniques like tracking shots, dark settings and casual costumes are used, but gore and stereotypical criminal representation are avoided to prevent predictability. Titles follow conventions of placement and fonts are simple rather than overly animated to not overwhelm audiences.
