White Oleander features another Oprah’s Book Club heroine, the kind who earns nobility and respect through contrived suffering. In this adaptation of Janet Fitch’s novel, a 15-year-old girl (Alison Lohman) is shuttled among a series of foster homes where she survives shootings, beatings and suicides, among other traumas. What doesn’t kill you may make you stronger, but even an Oprah heroine must have her limits. With Michelle Pfeiffer, Renee Zellweger and Robin Wright Penn in supporting roles.
