As irksomely attitudinal as its title, this bubblegum sporting caper follows the fortunes of a delinquent gymnast with a heart of gold. On to the mat steps tiresome Haley (Missy Peregrym), who signifies her rebel status by wearing a Ramones T-shirt and concludes her flawless triple-backflips by pulling a sarcastic face at the judges. "This isn't the real world," Jeff Bridges' coach explains at one stage, as if the film's Barbie-doll inhabitants and bumper-sticker dialogue hadn't already made that clear.
