Ben Affleck and Gwyneth Paltrow in BounceBOUNCE

Writer-director Don Roos might never be a great filmmaker - his staging is obvious in that Kevin Smith way (a lot of two-shots of characters talking) and there's no real visual life on display. But he's wonderful with actors, and he has a great ear for dialogue, writing realistic lines that can flip in a moment's notice to something truly comic or poignant.
