The document discusses conventions of thriller films and how Out of Depth challenges some of these conventions. It notes that typical thrillers use low-key lighting to create suspense, while Out of Depth uses naturalistic lighting to maintain realism. It also discusses typical character archetypes in thrillers - vulnerable protagonists and evil antagonists - and how Out of Depth follows these with a teenage girl protagonist and an unknown stalker/murderer as the antagonist. The document analyzes how Out of Depth uses camera techniques like point-of-view shots to build suspense, as well as opening with an inciting incident like many thrillers.
