It really doesn't have a following, beyond theatre cognoscenti. Sure, WE love it, but I'm not so sure that general audiences do. That original Broadway production was as staggering a creation as anything I've ever seen, before or since, and even with critical raves, eight Tony Awards, two great star performances (and two great star replacements), it didn't run, and lost most of its investment. And the revival, even with a Frank Rich rave, couldn't fill the 600 seat Circle in the Square after a few months.
