The Shakespeare plays recouped in week 12 of an 18-week run. Their recoupment is a laudable accomplishment, no doubt, but I daresay it's not "rather quickly" and, had they not offered the $25 seats, there is a reasonable argument to be made that they might have recouped a week or two sooner. So they get all due credit for their generosity, but extrapolating from their success that all plays should do it is not a responsible recommendation.
Also FYI, Radcliffe is only doing 14 weeks and though he is well-known, it's not a natural fit like Rylance in Shakespeare nor does it have the gimmmick of two plays in rep and/or the gender reversal (in "Twelfth Night"). Indeed, it's a terrible title for commercial ticket-selling purposes in New York.
So...instead of lambasting the producers for not being generous enough (!!), can't we be pleased that they are offering regular price $27 tickets to the general public at all? The level of entitlement/expectation is really quite mind-boggling. FindingNamo's point is spot-on.
