This is why this whole thing drives me up the wall from a business perspective, because Wicked is already old hat in 2022. In 2010, when Wicked was the shiny, new Broadway sensation, I could understand going two parts. Still think it would be terrible creatively and Part II would still probably get a Mockingjay-style fall, but I at least would understand doing this as a way to cash in on something that's super big.
But in 2022, the normies that don't care about Broadway moved on from Wicked. Hamilton's now the new sensation for the GA (Disney+ arguably did a lot of heavy lifting on its longevity, though that will probably lose its position in about 5 years), and even Frozen has stolen a lot of Wicked's thunder as the flashy Idina Menzel musical about female empowerment and villain deconstruction. I can't think of the last time I've seen it brought up in non-Broadway circles.
