Nice post. Beauty according to Western standards have been quite rigid in the past. From a marketing perspective, beautiful or pretty "sells" and we just have to accept the role we play in contributing to that.And this comment just drives the point home in how marketable corporations consider pretty girls to be (and the damage that does to society). There's nothing wrong with being pretty, but there's also nothing wrong with being not so pretty either. The problem is that due to the marketing BS surrounding us and the glorification of external looks thanks to beauty pageant mentality, society is being conditioned to accept and embrace the notion that the prettier you are, the better you are (and the uglier you are, the lesser of a person you are). That's the damage this does to society. Far more than some pirate animatronics chasing women around in a ride whose plot makes it excruciatingly clear that such behavior is evil and if you do it, you'll be cursed to suffer for all eternity.
You know another well known Disney story that showed us somewhat similar scenes? Hunchback of Notre Dame, where Frollo lusts after Esmerelda and tries to force her into a relationship with him (setting Paris afire to try to get to her). And you know what happened to him? He was killed and the movie makes it crystal clear that he was going to suffer in hell for his crimes.
I think movie-goers would more than "forgive" (sad to use that word in such context) an ugly princess if they went the extra mile to make her an interesting character. I certainly would, it could be incredibly cool. And I don't mean interesting in the same way Snow White is. I mean give her an complex story and personality. If the movie was as good as Disney's renaissance-era films and before, I would definitely embrace it. It could be a very cool inverse of the Beast or Quasimodo.
Our society has evolved in how we perceive beauty, it's much more diverse than it once was. What is considered to be beautiful is really subjective and ugly can be just as beautiful, if not more -- it just depends. This is why people love villains. The Broadway show is Wicked is a huge hit centered around the tragic story of the wicked witch. I'm sure no one would be interested in seeing a Broadway show about Glenda, The Good Witch. I'm also looking forward to seeing Maleficent with Angelina Jolie even though she gave me nightmares as a child.
