Todorov's Theory!

Todorov's theory of narrative:

Todorov is a bulgarian philosopher who was a literature writer and he published twenty one books. Todorov felt that all stories start in a state of equilibrium which is then disrupted, setting in motion a chain of events. The resolution of the story is the creation of a new or different equilibrium.

Equilibrium: State of well being and normality between the protagonists
Disequilibrium: Normality is disrupted due to a conflict or an occurrence of an event
New Equilibrium: The outer force is defeated and a new state of well being is acquired.

Another simple way to look at Todorov's theory:

• A state of equilibrium 
• Disrupted by an agent of change
• Leads to a process of final resolution 
• Return to a new equilibrium 

I decided to apply his theory on the film 'Texas Chainsaw Massacre 2013." Here's the trailer for the film:

• Equilibrium: They first arrive at the house all relaxed thinking it's a holiday. They are surprised that Heather has inherited a mansion in which she can enjoy with her friends.
• Disequilibrium: The thief plans to steal items in the mansion and ends up dying in the cellar as Leatherface is there. From there, Leatherface starts to kill Heather's friends. 
• New Equilibrium: At the end, there is a new start of Leatherface and Heather because they discover that they are cousins and they end up living together. 

By analysing and applying Todorov's theory to a horror film, it makes me think about what kind of storyline I would want to feature and if I want to follow Todorov's theory itself in my trailer.
