I recently started Curb Your Enthusiasm and Larry David's semi-autobiographical character is a good comparison to the Lena Dunham character. Curb's Larry David is one of the more flawed characters on TV but somehow it makes me care about him all the more. He never feels smug or oblivious.
Haha, all this meta talk over one episode. Clearly the show hit a nerve. Though I don't think anyone would particularly care about it if HBO and the critics hadn't crowned Lena Dunham The Voice of Her Generation out of freaking nowhere.
