Jennifer Weiner's book was a page-turner, so why is the film such a snooze? As dissimilar sisters Maggie's a learning-disabled sexpot, Rose is an emotionally impaired frump Cameron Diaz and Toni Collette conjure believable sibling rivalry (Maggie boffing Rose's beau while wearing Rose's slouchy open-toed stiletto boots really stings). But even glamour grandma Shirley MacLaine can't spice up this standard-issue chick flick.
EXTRAS Out-of-his-element director Curtis Hanson (8 Mile) illuminates some subtleties (a handheld camera captures Maggie's ''looseness''; the art on Rose's walls reflects loneliness), and hearing the bit players actual Florida retirees discuss acting is a kick. ''It got a little...irritating,'' says one sassy senior. Still, 35 minutes of making-ofs are as skimpy as a faux-Manolo strappy sandal.
