For some quick context, Elphaba, AKA the Wicked Witch of the West, is pretty infamous for her green skin. She’s essentially othered from day one and hated throughout the land of Oz, so much so that the villagers celebrate her death in the opening sequence.
Given that the entire premise of the movie is based on Elphaba being othered due to her skin color, fans online are now discussing how Cynthia — a Black woman — playing the role added a new layer of depth to the character.
