So what if she came from the projects, she had much more character than any other princess (I mean really, Arial from The Little Mermaid was in a word shallow, she couldn't accept who she was. Of course that's debatable but moving on). And that just showed how much more of a role model she is for her never-giving-up attitude. She went from the projects to running her own booming restaurant-- now that's dedication. And Disney was just trying to be historically correct--what do you want them to do? Lie and not be aware that the majority of black people, or people in general I suppose, back then were poor? Not to mention the great family ties she had (aside from the fact that Disney ALWAYS has to kill one parent).
And honestly, who cares if she was a frog practically the whole movie, we take steps to reach a destination, give it time. Hopefully, this is just the beginning of equal, multi-race entertainment. I kind of have a feeling that the only people who noticed that are people who are trying to prove they are aware of racism in the world. But really, if you are a person who just noticed there weren't any black princesses before the movie even was being advertised, give yourself a pat on the back.
This movie was great and I am excited to see more of the likes of it.
