The document discusses several theories about narrative structure and how they apply to the film Halloween. It summarizes that Todorov's theory of equilibrium, disruption, attempted restoration, and new equilibrium is subverted in Halloween as the disruption occurs at the very start. It also analyzes how some but not all of Propp's character archetypes are present in the film. Finally, it examines how Straus' concept of binary opposites between good and evil, day and night are reflected in the film through the hero Laurie and villain Michael Myers.
