In the final minutes of “After Hours” (1985), two thieves, after having finished a dishonest night’s work, engage in some impromptu art criticism. Whilst stowing a life-size plaster effigy lifted from an artist’s studio into the back of their van, the first of our anti-heroes makes an observation: “Art sure is ugly, man.” To which his compadre responds: “That’s how much you know, man. The uglier the art, the more it’s worth.”
