If you're not a fan of Will Eno, this play probably won't change your mind. But MCH is excellent in it - run time was exactly 60 minutes, and it flies by. Do not sit close if you don't want interaction, as he spends the entire show direct addressing the audience. And yes, there is audience participation.
In terms of genre/writing, I feel like the direction & acting really surpasses the weak and irreverent text.
Is it a must see? Absolutely not. But for $35, a brisk hour of theater, and a great intimate performance with MCH, it was well worth it, and I would recommend it.
