Buried beneath the bawdy humor was a valuable message. People can't figure out how to solve their problems when they just feel sorry for themselves. They lose sight of the people around them in their self-obsession. It's not all about you. Look around. People want to be helpful. Be helpful yourself. This is the rare Hollywood comedy that is not just fart jokes.
Could've done without the montages, and it lost points when it diverted too far from the kind of restrained realism that make the funniest bits so good. McCarthy is so good that she doesn't need to be saddled with her broader jokes. Wiig's genius is that, even when she's making me laugh out loud (I'm thinking of the shower freakout) she maintains a reality that both heightens and transcends the comedy.
Actually, it's a 3.5 because 1) the performances had a special comedic quality that isn't quite usual to witness in contemporary mainstream American comedy (that's probably due to the fact that it was women over 30 having the lead roles) and 2) there were some moments that made me really laugh and not just smile.
