Yeah, I think Mulan was a way for them to branch out culturally in their revisioning of fairy and folk tales. Pocahontas was an attempt at that, but received quite a bit of backlash after a time, and I think Mulan was more well-done in reflecting the culture of the time and the legend it's referencing.
One thing that we talked about in folklore class last week after watching Cocteau's version of Beauty and the Beast is that though it's quite popular in the folktale scene right now to protest "Disneyfication," Disney actually does a pretty good job of sticking to the spirit of the tales. I wish I could remember what my friend Laura said about that, because it was good. It was in the context of the form of the tales--we've been studying Max Luthi, who argues that one of the main reasons folk tales are so fascinating is their structure. Folk tales have a definite form that's different from any other style of storytelling--plot-driven, flat characters, etc. Luthi argues that it is this flat style that brings to life a number of things, that it's an abstract form of storytelling, outlining the characters in stark contrast from each other and their surroundings, with no past or future, externalizing all emotions and motives--goodness is shown in actions, not emotive description, if that makes sense.
I'm veering away from Disney, though. I forget how it relates to Disney. But it does.
