Examples of this type of film include George A. Romero's Night of the Living Dead, Tobe Hooper's The Texas Chain Saw Massacre, John Carpenter's slasher film Halloween, and Wes Craven's Scream.
These include the disruption of everyday life through violence, the crossing and violation of boundaries, and a critique of rationality as a reliable framework.
It also rejects traditional narrative closure, instead offering open-ended or unresolved storytelling.
Additionally, it creates a confined experience of fear for the audience, fostering a sense of immersion.
