Margot at the Wedding

This movie is about Nicole Kidman's character who is a self-absorbed nut-job. Her family's problems are splayed out in all their uncomfortable glory for us to see - the lying, cheating, hurtful back-stabbing, gossiping, masturbating glory. It's a bit like watching a horrific car crash, but one that involves a clown car (played by a very-well cast Jack Black) so you don't feel so bad about wanting to watch the crash unfold before you.
