Tzvetan Todorov was a Bulgarian-French theorist who proposed a five stage narrative theory in 1969 consisting of an initial equilibrium, a disruption to that equilibrium, recognition of the disruption, an attempt to repair the disruption, and a return to equilibrium. He suggested that all films follow this pattern, though the theory may be too basic to apply to narratives with cliffhangers or unhappy endings and would best suit fairytales.
