Todorov

Todorovs theory was set a basic structure for all narratives.  He said that all films start of with an equilibrium; a calm period where everything is balanced and steady. then has a disequilibrium; a disturbance  which is a period of unsettlement. Then after that  a narrative has to have a new equilibrium; a sense of restoration / new beginning and a state of peace for the protagonist. This is the simplest form of narrative and can be referred to as 'classic' or 'Hollywood'.
