Based on Anna Quindlen's bestselling novel, this is a mother-daughter and father-daughter story, two for the price of one. But director Carl Franklin also tries to inject a police-mystery angle that it neither needs nor will support. Renee Zellweger plays a young writer on the rise, who has finally got her break for a New York magazine. While home for a birthday party for her nearly famous writer father (William Hurt), she learns that her mother (Meryl Streep) has been diagnosed with cancer. Then her father does the unthinkable: he all but commands her to put her career on hold to take care of her mother and nurse her through her illness. Dad, a popular college professor who has never received the literary acclaim he always believed he deserved, essentially checks out--and daughter must play parent to her mother. Strong performances by Streep and Zellweger give this parent-child relationship the heart--and the anger--of the real thing, while Hurt seems slightly disembodied as the self-involved father whose needs have dominated both women. Still, the detective-story aspect (the film is told in flashback, as the cops try to discover whether someone slipped Mom a fatal dose of morphine) is a construct that could have been done without. --Marshall Fine
