Deep inside JUNO is the tiny but true heartbeat of American film. Director Jason Reitman has an extraordinary control of tone, shifting sympathies and a clear respect for the fully realized characters created by screenwriter Diablo Cody. The result is a surprise in almost every scene as cliches are upended and life is celebrated at every turn. Ellen Page delivers the breakthrough performance of the year - one that embodies the comedy inherent in being a misfit and the strength that comes when facing life's biggest challenges.
