The document discusses several theories of narrative structure:
- Vladimir Propp's theory that Russian fairy tales follow a structure of character types like the hero and villain who drive the plot through their actions and motives.
- Todorov's theory that most narratives follow a basic structure of equilibrium, disequilibrium caused by disruption, and a new equilibrium restored at the end.
- The classical Hollywood narrative structure which resolves all mysteries by the end to give a sense of closure. Causality and cause/effect relationships are also important aspects of narrative.
