A wonderfully nubile young Mary Elizabeth Winstead glows is her role as a shy but talented dancer. I am not sure Mary Elizabeth performed all of her dance scenes or had a double, but the point is probably moot. Quite a credible movie, unlike 'Flashdance' who had Alex as a welder (as if) by day and a dancer by night. Dancing is a hard career path, like a pro athlete, riddled with injuries and of short duration. Most dancers and pro athletes are done by their early thirties, and there are limited coaching and commentating roles after that. This movie is sort of a G-rated 'Showgirls' with a beautiful brunette instead of a beautiful blonde in the lead role, and it is less tacky. OK it is light and fluffy but that is just what the world needs now.
