Just saw the "Runt" episode of "30 Rock" on cable and am amazed at how much the show evolved from the first season. First, the focus was on the writers, now they're background characters. Second, when Liz had a problem she discussed it with Pete, now it's Jack, and finally it's so surreal now, comparatively speaking this episode was a drama (watch Tracy's speech about diabetes) ! Rip Torn plays it totally straight, two seasons later he'd be over the top.
I'm not complaining, as the show got more surreal it just got funnier. All signs seem to point to just one more season though.
(Read Bossypants, Fey touches on the difficulties of being a female in charge that this episode focuses on.)
