I like Disney movies, though they are almost never my favorite version of a story. So, original is better than folklore or fairytale for me. Fantasia was always my favorite as a kid (though even then I could not understand why they felt they had to tag the ave onto the end of Night on Bald Mountain)
Belle is my favorite Disney princess - because she falls in love with Adam when she doesn't know he's beautiful, and because he woos her with his library. That's my idea of romance. If it had been around when I was a kid, it might have become my favorite.
