The most bizarre example of this trend was Feministing's take on 30 Rock a few months back, in which the writer came so close to getting the joke:
The most frustrating thing about 30 Rock, an otherwise excellent show, are the constant references to the fact that Tina Fey's character Liz Lemon is ugly. The thing is, Tina Fey fits conventional standards of female beauty almost to a T.
That's why it's funny! The entire Liz-Jenna dynamic set up by the show is one big joke: Liz, who is constantly referred to as plain or homely, is naturally beautiful. But Jenna, the heavily made-up blonde TV star who always talks about her good looks, has that faded-beauty look to her: you can tell that she was attractive when she was younger, but her refusal to deal with her age gracefully means she always looks like she's grasping (unsuccessfully) for some of her past glory. Hence her absurd dismissals of Lemon's looks: that she could never be an actress "because of her neck" and so on. It's a joke. Maybe we should just laugh - and refrain from suffocating the show's humor with forced political readings of our favorite episodes. (Unless I'm doing a political reading. Then it's OK.)
