I call that "Disney-fying" things, a la' "and they all lived Happily Ever After. The End. Until next year's sequel." But to be fair, I don't think Disney actually claims the originals as "their own," so much as takes original material and "makes their own version of it."

I do hafta give props to Disney for taking such Pagan stories and presenting them to the American public as early as the 50's, when the US was still quite overtly a Christian nation.
