Film theory has nothing to do with film. Students presumably hope to find out something about film, and all they will find out is an occult and arcane language designed only for the purpose of excluding those who have not mastered it and giving academic rewards to those who have. No one with any literacy, taste or intelligence would want to teach these courses, so the bona fide definition of people teaching them are people who are incapable of teaching anything else.
