Brave is one of the rare original films. It's about a Scottish girl whose mom gets turned into a bear through magic and she has to rescue her. Frozen is a retelling of Andersen's Snow Queen with two sisters instead of a sister and a brother. Tangled is Rapunzel. OH. And then there's Moana, which is also original, but it's based on Maori/Pacific Islander legends. And then Coco is sort of vaguely based on Dia de Los Muertos legends. Hence the debate.
