C'mon get real people [spoilers]
[spoiler alert]
This is a mostly depressing film about sex, drug addiction, Alzheimers, deceit, and depression. The tone is extremely nihilistic. If most of the people don't recognize that, I'm wondering is it because their own lives are possibly just as empty. Look, this is NOT a comedy. Anybody who thinks this movie is a comedy should look in the mirror. The ending -- extremely ironic. But the ending does NOT make this movie a comedy.
The saving grace for this movie, and it is a big one, is the ending. I must admit the ending is brilliant.
