Todorov proposed a theory of narrative structure that states narratives begin with a period of equilibrium, followed by an event that causes disequilibrium and unrest, and concludes with the protagonists achieving a new state of equilibrium and resolution. His theory suggests all media follows this basic pattern of introducing characters in a calm state, disrupting that calm with some challenge or problem, and ultimately restoring order and peace by resolving the disruption. The theory views narrative as having two parts - a structure defined by the equilibrium shifts, and various elements like images and texts that create and resolve situations within that structure.
