For that matter, Star Wars also has that classic good vs evil theme. The rise, fall and redemption of the main antagonist. The son's struggle to be better/stronger than his father. The powerful allure of "black magic" at the cost of your soul. Disney could print their own money if they did a fully fleshed out Star Wars World.
I also think Middle Earth would have been a much more appropriate IP for Animal Kingdom. It also would have made bank. It would capture essentially the SAME audience that HP captures for Universal. It could keep them on Disney property, which makes Disney money.
