The Princess and The Frog and Soul, are the two Black firsts—the first Black Disney Princess and the first Pixar movie with a Black lead.
Each attempting to gain representation clout from young and old people who have been socialized for generations to view the company as synonymous with universality. Now, this criticism of Soul and Princess and the Frog, or really any polarizing BIPOC animated creation does not dismiss the feelings of those who may feel represented by it—or dismiss the one BIPOC creator works like this bring on for "authenticity."
It is calling out the failures of crafting diversity around a theme or topic, not build to actual deal with Blackness, or otherness, that lead to the film ultimately failing to really say anything—at least to this lady.
