Thank you for that review, Matt. I haven't, but I've heard very different reactions to it. One friend who has, well, lived long enough to see the underbelly of human relationships loved it and said "it's a realistic depiction of life in a dysfunctional family, and if you've experienced that, you can recognize the struggles." Another friend who is younger and very idealistic ("other people have problems" kind of person) was ANGRY after seeing it -- she said it was a total waste of time and money and she couldn't understand why anyone would want to make a movie that depressing.
I'm waiting for it to move on over to the $3 movie theater because I'm cheap...
