Walt and his artist crew created many wonderful things. One of the unfortunate after-effects of many of his major animated features is that all of the women characters (Snow White, Cinderela, et.all.) lived happily ever after. This idea has been ingrained in the minds of many, if not most, little girls the world over, but especially in the USA, since 1934.
It just doesn't happen this way, kiddo.
Perhaps the stories should have ended as "They lived happily ever after...for a while."
Maybe we take this stuff too seriously. Just sit back and enjoy! There's no subliminal message in a Disney movie.
(I think!)
