My Sister's Keeper is almost two hours long--nearly as long as my quiet weeping jag lasted. So in many ways, director Nick Cassavetes (who previously made you guiltily sob through The Notebook) nailed the necessary pathos of a family's struggle with their teenage daughter's cancer. But the trials of terminal illness can be a bit like shooting fish in a barrel when it comes to jerking tears from an audience--so even while clutching your hanky, you may still walk away wondering if you actually liked this erratic film. by Courtney Ferguson
