As "Juno" reveals, the run-of-the-miU teen nonconformist is, as the screenwriter finally realized about herself in college, "a noisy, dramatic attention whore." [Cody] is too recognition-starved to stick to the party line about how the alterna-kids are free spirits. Instead, she's made herself a celebrity by spilling the beans about punkette girls Uke herself and Juno. Why do they teU guys that their three favorite bands are (to quote Juno) "Iggy Pop & the Stooges, Patti Smith, and the Runaways?" Because, to over-generalize, pretending to obsess over old pop culture minutiae makes smart boys notice them and it gives shy boys something to talk about with them.First, though, let's dispose of the controversy over the purported poUtics of "Juno." Is Juno betraying feminism by choosing adoption over abortion? Sure. Yet there's no mystery why Hollywood heroines (as in the recent "Knocked Up" and "Waitress") almost never have abortions: because babies are adorable and abortions are hideous. Nobody-including, and perhaps especiaUy, pro-choice ideologues-wants to think visually about abortion.
