As a descendent of character portrayed I can insist that in no Polynesian culture is Pele a witch, nor Maui without Hina. Further I can insist that history has proven DizzyLand to be misogynistic and rasist and inaccurate and to practice and encourage ethnocide from Mulan to Moana to Pocahontas and from the Grimm's. Fairytail were based in fact and lay moral which DizzyLand has glossed over. 
In Moana they have prostituted Pele to magic whereas she is a real person in our kumulipo.
Should I re-write your history and portray it for best commercial value?
Let's make JFK and George Washington or Jesus black. Martin Luther King a wizard. Not cool right?
