Two observations, really.
1. I am a garbage-brained glutton for punishment for continuing to watch American Idol. That is not a judgment on anyone else who watches it, but a solid assessment of myself based on my own constantly infuriated reactions to it.
2. It really seems like the top 12 "boys" were explicitly encouraged to be as individual and quirky as possible, while the top 12 "girls" were encouraged to conform both in style and song choice to some weird amalgam of a high school talent show contestant and a pageant entrant. Which is not to say that none of the girls were quirky or talented or whatever, but only that the spectrum of acceptable quirkiness for the girls seems a lot narrower than it is for the boys.
I know. No doy. It's American Idol. But it's way more obvious than usual, even.
