Material Girls

It's less substantial than cotton candy, but Material Girls is as slickly produced as one of the Marchetta TV spots.

The Duffs are certainly cute together, but not even their natural chemistry can enliven all the preachy bits about hard work and the meaning of happiness.

The real-life sisters Hilary and Haylie Duff star in this incompetent spin on the poor-little-rich-girl story.

The most shocking moment comes during the closing credits, when it's revealed that not one, not two, but three screenwriters were responsible for a plot that someone seems to have hastily slapped together after taking a walk around a Sephora outlet while listening to "Beat Of My Heart" on loop.

It's not "Clueless," just clueless.

Mainly offers fodder for tweens who fantasize about glamorous Los Angeles lifestyles where everyone is skinny, rich, and on Prozac. It's a film where gays and minorities not only fit into stereotypes, but embrace them.

There is plenty of blame to go around for this laughless mess.
