PARK CITY -- If you're going to do teenage angst and hedonism in a movie
, it's oh-so-much-more exciting among the rich. When they get loopy on drugs, indulge in promiscuous sex or get into those little misunderstandings that end up with guns going off, the lighting, decor and attire are far better than in grungy inner-city movies. So Joel Schumacher's "Twelve," the latest expose of self-indulgence among privileged teens, is sleek, giddy fun. The girls and the guys are hot, and every get-together takes place inside posh homes on Manhattan's Upper East Side.
