here's how that movie would go.
batman, in pursuit of the riddler, is forced to deal with the fact that his acting as batman has become an obsession of his own, an outlet for his own madness. he attempts to confront this madness, but alas, he combs his hair down over his face and struts down the sidewalk pointing at people and saying, "hey there! yea!" and then he goes to a jazz club and dances awkwardly for 15 minutes.
