The “PC Principal” theme of this season is a satirical masterstroke, but it hasn’t always been perfect.

It is good so far.

they need to branch out a bit - its getting a little repetitive.

..of course they are probably going to do only about 6 episodes this season and then take the next 4 years off, so we shouldn't complain about the new episodes.
