Rachel (Rosemarie DeWitt) is indeed getting married, but it's her sister, Kym (Anne Hathaway)—an ex-model, lifelong drug addict, and alcoholic who's been in and out of institutions since causing a family tragedy as a young teenager—who demands to be the center of attention. Jonathan Demme's latest is a difficult, sometimes tiresome film, but it's also emotionally ambitious, and it offers a modern portrait of family life that depends very little on convention. by Marjorie Skinner
