Have the bad guys taken over?Over at Vanity Fair, Julian Sancton has an analysis of why superhero movies are so hot lately entitled 'Why America Worships Superheroes'. One of the most interesting things about his write-up is the inclusion of The Joker from 'The Dark Knight' in the photo used to illustrate the piece. Joker, of course, is not a superhero but a super-villain. Of the four characters in the photo, the only one that isn't a superhero is The Joker. More to the point, conspicuously missing from the photo is...Batman.
