That's a keen little guide to the genre, yes indeed!
It reminded me, in my animation career we used to suspect that the executives had three big wheels in a secret room somewhere that they would spin to come up with their new animated movie ideas. One wheel would have things like "Barnyard animals, martians, toys, bugs, etc." for the cast of characters, then another would have "outer space, ancient Egypt, darkest Africa, remote island, the big city, etc." for settings, and then the third would have all the plots from all the great works of literature and lore, and other movies too, like, "Taming of the Shrew, Pygmalion, The Incredible Journey, MacBeth, Lost Horizon, etc." Then they would simply spin the big wheels, wait for them to stop, and end up with, "Zoo animals in the big city making an incredible journey to get back to the wild" - which, BTW, is currently in production at Dreamworks.
