Is this movie too realistic for you?
Like some posters have noted before, this movie does an excellent job of being realistic. But apparently that's a problem for many viewers. People used to typical Hollywood movies are having a hard time digesting the fact that Hank made up with Carla, the way the judge died, the youngest brother's mental handicap, the poop on the bathroom floor, the way that Sam's (the ex girlfriend) subplot ends, etc., etc.
This is what real life looks like: it's complicated, there aren't cute short answers for everything, and things can get ugly. Not every subplot gets resolved with a neat, cute, happy ending.
