My question in these cases is always, "Why?" If the production is obviously not working out financially, why keep it open? Are the producers just so desperate to have something on Broadway that they are willing to take the hit? Are they afraid of admitting such a big financial failure that they're willing to have an even bigger financial failure? Do they have some ridiculous hope of getting a boost from Tony awards?
If they want to take this on an arena tour or to Vegas or wherever and advertise it as "direct from Broadway", that standard has been met.
