I enjoyed this show a lot, and I wish them nothing but the best! But yeah, I don't see this going to Broadway either. Not only do I worry about its commercial prospects (although admittedly the running cost would be very low) - I just don't think it needs to. Not every good play needs to run on Broadway; that isn't the ultimate measure of success. Two runs at MCC, a run in LA, a special Drama Desk for the cast, and likely a healthy licensing future, are not things to scoff at. In fact, I would argue that those achievements are more significant than a short run on Broadway and a couple of Tony nominations
If I'm wrong, and it does go to Broadway, I'll be very happy for them. Like I said, I wish them nothing but the best!
