It explains Todorov's five stages of narrative structure, including equilibrium, disruption, recognition, attempt to repair, and new equilibrium. Propp identified eight common character types and 31 potential functions in narratives. Levi-Strauss discussed how binary oppositions like good/evil drive conflict and resolution in stories. Barthes' enigma code explained how narratives use partial explanations and codes like tension-building to intrigue audiences into further viewing.
