AVClub: The previous episode of Vice Principals saw the show finally start to establish itself. What’s been a rocky, unfocused season started to come together, as “Circles” dug into the character psychology of Lee Russell. That focus on character allowed for a certain amount of depth to shine through. Suddenly the crass nature of the humor—especially Russell’s continuously vulgar and crude behavior—wasn’t simply shock value, but rather a way of presenting how broken some of these characters are. With the characters more firmly established, “The Foundation Of Learning” sees Vice Principals switching gears a bit, going for a more low-stakes, low-key approach to the story its telling, and the show is better off for it.
