This document discusses several narrative theories and how they apply to teen slasher films. It analyzes Todorov's narrative structure of equilibrium, disruption, recognition, and new equilibrium. While most films follow this structure, teen slashers are more irregular in their ordering. It also examines Propp's character types and narrative functions, noting teen slashers don't always have clear heroes and have multiple "princess" characters. Finally, it applies Levi-Strauss' concept of binary oppositions and Barthes' "enigma code" to teen slasher conventions like revealing the killer's identity.
