Frankenweenie all the way since I'm a pretty big Tim Burton fanboy. But Oz: The Great And Powerful along with Monsters University would also be almost certain buys.
Dragonslayer. Not on bluray in the UK yet and a hugely overlooked movie. Dragon was animated by the team that did the Hoth Attack in 'The Empire Strikes Back'. Maybe a bit obscure when looking at the Disney canon but to me one of their better films.
