The best thing about that episode was that they filmed a number of scenes at the Public, and, specifically, inside the Anspacher. The show itself is pretty bad, but I do enjoy seeing the theatre people and the NYC locations. Tavi Gevinson, Adam Chanler-Berat, and Jason Gotay are series regulars as teachers, and Laura Benanti is also featured.
From what I've seen on social media, a lot of people can't stand Tavi Gevinson in her role, but I think her over-expressive/goofy acting adds some much-needed levity to an otherwise too-serious show.
