Absolutely everything. The music/lyrics are spot on, the performances kick ass and the direction is both clever and unobtrusive. Highly, highly recommend.
What I didn't like
When at the Black Box space, make sure you don’t sit on the sides. Both shows I’ve seen there have been directed more for a proscenium setup than moderate thrust so you see a lot of profiles and the back of a lot of heads.
My overall impression
Run, don’t walk. Absolutely hilarious. Slick, funny, professional and concise.
