Claude Levi-Strauss was a media theorist who studied hundreds of myths and concluded that humans make sense of the world by seeing binary opposites such as good vs evil, weak vs strong, and man vs nature. His theory was that narrative structures are based around these conflicts between binary opposites, which are at the climax of the story. Levi-Strauss' theory suggests binaries like a generic middle class family contrasted with the protagonist selling herself for income in one film.
