HAIRSPRAY
Adam Shankman's Hairspray, adapted from the long-running Broadway musical, is like a sugar high that lasts 105 minutes. Yet it's a high that you don't crash from afterwards; days after seeing it, you may still find yourself in thrall to its infectious exuberance. Not only is the film the happiest surprise of the summer, it's the happiest surprise of the year - a giggly pop fantasia exploding with exhilaration and imagination. Audience members who don't like Hairspray won't be people who don't care for musicals; they'll be people who don't much care for movies.
