I see it today but so far not only is it referencing the 1939 film but also there's little winks and nods to other Oz movies and books. Similar to Dark Universe, Wicked is reimagining Oz but also still playing with what's familiar. I think it's a no-brainer that they bring it to the parks. In-house IP with deep connections in culture going back to 1900. Oz is timeless, and only more children will be introduced to the world through Wicked.
