Theories

The Todorov narrative structure is the theory that every movie has a equilibrium(where everything is normal and happy)then comes the disruption(where something goes wrong), the resolution and lastly the new equilibrium where everything goes normal again and everyone is happy. This theory can be demonstrated through the scene in ‘Toy Story’ when Buzz Lightyear arrives. 

In the scene there is no equilibrium however it jumps straight to the disruption, which is buzz lightyear.

Then comes Woodys attempt of the resolution where he tries to bring everything back to normal by trying to prove to the rest of the toys that he's just as good as Buzz lightyear

Lastly the scene gets a new equilibrium but not due to woody, however it was because Buzz lightyear took over Woodys position as the leader and everything went back to normal but with him instead.
