I never heard the author of the comment, "there are only eight plots for a story" (and prolly any one of us could fill them in - with only slight variance ?? if we tried)
The Greeks did a pretty good job of making Epics of about each one. Ovid pretty well cooled 'romance'. Etc.
But I see your point - Disney is about as innovative as the Beast AND they already DID that one! Beauty and Der Beast. Still and all.. our Primary food group here is, Saccharine. Y'know?
