I dislike the Meg bashing because it comes off as sexist, and a bit mysoginistic. They say that they bash Meg because they don't understand teenage girls, and Mike Henry said that Meg deserves to be bashed because she's a girl (he's joking, but I digress). I'm not exactly a feminist (not even female in case you couldn't tell), but I think in this day and age female characters should at least be interesting. I can't help but think that girls make inherently more interesting characters than guys in many ways.
I just wish the characters would, you know, have a soul, and a reason for existing other than to make money for big corporations by using cheap humor.
