I think that for a long while it was playing at The Court Theatre, which is not a theatre one sees easily from the main drag of Broadway. With that being said, I think that there were a lot of people who didn't know it was around after playing the American Airlines Theatre on 42nd. It was making money and enough to move when You're Welcome America wanted the Court to move to The Helen Hayes.
It is very close to recouping but only time will tell if it does so before it closes. I saw it and I loved it very much. Very different from what I have seen before and I will see it again before it's time on Broadway is done.
