Diaz is passable and Collette is great. A very emotional film. Not great and a bit too long. It starts off pretty predictable, but gets better as it goes.
Leonard Maltin/Plot synopsis:
Straight-laced Rose breaks off relations with her party girl sister, Maggie, over an indiscretion involving Rose's boyfriend. The chilly atmosphere is broken with the arrival of Ella, the grandmother neither sister knew existed.
