If it's scoring as bad as we think it is why not just go ahead and can it? They could literally do something like "to finish out 50 years of magic we are bringing back the fan favorite Happily Ever After to the Magic Kingdom this fall....." and people would go beserk. I know there is the logistics of changing firework shells, projections, etc., but it seems like such an easy call to make.
Disney baffles me on stuff like this - things that are a slam dunk they almost look for excuses NOT to do, while easily finding reasons to do things that make no sense from a guest perspective.
