Strauss believed that we understand words in relation to their opposites, known as binary opposites. Examples of binary oppositions in media include hero/villain, good/evil, and sane/insane. Traditionally, binary oppositions in films were simple, like good vs. bad, but have become more complex. The Harry Potter films effectively portray the binary opposition between Harry (good) and Voldemort (evil) through their appearances and roles in the story.
