There's a certain exuberance, a "you go girl" spirit of defiance and self-reliance to this Mo'Nique vehicle that's undeniably appealing -- especially for its target audience of overweight women. But beyond the star's obvious enthusiasm for the project, there isn't a lot going for Phat Girlz, which looks cheap and falls apart after the first act. The plus-size comedian stars as Jazmin, a sales assistant who dreams of becoming a fashion designer. One day, she and two friends go to a Palm Springs resort for the weekend, and things start looking up when it turns out there's a convention of Nigerian doctors in town, all of whom happen to be incredible physical specimens who revere large ladies. Once Jazmin catches the eye of sexy Doctor Tunde (Jimmy Jean-Louis), however, the story collapses: A very minor misunderstanding separates the two, and the plot goes back to the fashion stuff.
