"Disney likes to think of the Princesses as role models, but what a sorry bunch of wusses they are. Typically, they spend much of their time in captivity or a coma, waking up only when a Prince comes along and kisses them. The most striking exception is Mulan, who dresses as a boy to fight in the army, but--like the other Princess of color, Pocahontas--she lacks full Princess status and does not warrant a line of tiaras and gowns. Otherwise the Princesses have no ambitions and no marketable skills, although both Snow White and Cinderella are good at housecleaning."
She nicely sums up why we have some Princess products, but not to excess -- and certainly not on the walls. Walls are saved for characters that kick butt: Atomic Betty, Kim Possible and a hilarity-inducing drawing by Laurel of an eye patch-wearing blonde and a dog with the caption "We will save you!".
'Cause man, if I have to be saved, I'll certainly welcome someone that can run in heels. Being able to run in heels while wearing an eye patch is simply impressive. And pirate-y.
