With a little designer fairy dust, the dolls that learn life lessons through fashion are becoming real girls in their first live-action motion picture, complete with plenty of "be yourself" messaging and a down-with-the-kidz soundtrack featuring the hottest artists you've never heard of (plus Ashlee
Simpson). Chelsea Staub, playing a Machiavellian social planner, does a little diva pop. And you can almost see the zany, shopping-oriented montage scene in the Slumber Party Girls' Avril-fied punk-pop. Like Bratz, there's something undeniably cool about it all. It's all about the "z," baby.
