Any Polynesian anons care to explain what's wrong with it?
The person from this article says that Maui was shown as dumb and brutish, and there being no female goddess accompanying Maui like in their myths as some of the reasons the movie was inaccurate. But Moana was chosen by the Ocean and she is female. She is clearly the stand in for the female goddess from the myths. And Maui is never shown as especially dumb, just very exuberant.
And I get that they blended the disparate cultures quite a bit but they all share a root culture so why is it so terrible to blend the different customs together?
