Roland Barthes taught us the idea of semiotics, for example the colour red being associated with anger, danger, love, heat.
He also taught us about enigma, this is when the media manipulates the mind and then leaves the audience asking questions.
Tzvetan Torodov taught us that stories always start at equilibrium. And in order to return to equilibrium the character.s must overcome a series of obstacles.
Levi Strauss taught us about 'binary oposition' this is the study of oppositions within a movie (e.g. good vs evil)
