The document discusses different theories about analyzing stories and plots, including binary oppositions, Tzvetan Todorov's theory of narrative structure, Vladimir Propp's archetypal characters, and Roland Barthes' 5 codes. Todorov's theory proposes that narratives follow a cycle from equilibrium, to disruption, to character realization and attempted restoration of order, to a final restored or new equilibrium. Propp believed that typical character roles like heroes, villains, wise figures and helpers are commonly found across stories.
