Revealing HBO documentary takes a disturbing look at the issue of eating disorders in America by going inside the Renfrew Center, a Florida treatment facility where four very different women─a twin who's jealous of her sister, a divorced mother of two, a 15-year-old who inherited her mother's unhealthy eating habits, and the group's unofficial leader─each struggle with negative body image, society's obsession with being thin, and indifference from their health insurance providers. 102 min. Standard; Soundtrack: Enlgish.
