In alchemy the transmuting of materials between forms distills them to their purest elements. In film, the opposite is true. The more iterations, the more muddled things get. Hairspray is good at what it does but not everything it does is good.
Bright, campy and wonderfully light, Hairspray reminds us that fun comes in all shapes and sizes. It's also one of the few 'event' movies this summer that doesn't outstay its welcome. That's worth singing about, no matter what your name is.
Much as Hairspray serves as a showcase for the effervescent charms of newcomer Blonsky, its greatest trick is to revitalise the careers of a few old Hollywood faithfuls.
It's amiable, it's bouncy, it's got a sweet unknown in the lead flanked by a cast of bankable stars and, providing as it does an amiable and bouncy and sweet escape from a summer's worth of clunky blockbusters.
