An unreasonably entertaining movie, causing you perhaps to revise your notions about women's Roller Derby, assuming you have any.

Clicks on so many levels -- heartwarming family story, rough-and-tumble display of grrrl power and a secondary but tender and convincing romance.

Laced with good-natured hipster kitsch and endearingly goofy girl power, director Drew Barrymore's roller-derby dramedy, Whip It, is a gas.

Marcia Gay Harden is the picture’s treasure; watching her swell with concern at her daughter’s choices, you understand how hard it is to let go.

Barrymore’s casting choices are intrinsic to the success of the film. Lewis, under her rink name, Iron Maven, hasn’t had this meaty a role in maybe 15 years, while Wilson as the team’s shaggy male coach is a hoot to watch. Harden and Stern, as Bliss’ parents, create fleshed-out characters instead of lazy depictions of the paper tigers that grown-ups usually are in teens’ stories.
