Well, it's about time that a Pixar movie got a female writer and director, and perhaps even more importantly, a feisty female heroine, in this case, a princess who would rather be an archer. I have no objections to original storytelling for the Disney Princess franchise. But I do wonder if it might make sense to start adapting a second generation of classic princess stories.
The Grimms' fairy tales and legends of similar pedigree and provenance were all very well for the first and second Golden Ages of Disney. But one of the great fortunes girls of my generation and after have is that authors like Tamora Pierce and Patricia C. Wrede gave us heroines worth a hundred Mulans. Alanna of Trebond is a magician, a warrior, and a total babe (as well as a metaphorical advocate for reconciliation between the West and Islam). Cimorene works for dragons, defeats deeply obnoxious wizards, and makes one hell of a queen and an eventual if temporary single mother. I can see political troubles lurking for each series, but between the two of them, they'd provide eight terrific movies for young women. I'd love to see Emma Stone as Alanna, for example, but I think they'd work equally well with terrific animation. Somebody at Pixar should get on that, if they could stand to humble themselves and adapt someone else's material.
