The only problem I have with Maui---
he's drawn as a big goofball.
What is wrong with taking an Asian or Polynesian character and actually making him handsome. Asians in film and animation have to be odd/goofy looking?
I remember as a kid, people from India were always given goofy characters or faces, but with movies like Slumdog Millionaire or TV shows like Heroes, we're getting Indians who actually look nice.
At least the "male" lead in Mulan was decently-drawn, although the rest of the infantry was filled with goofballs (the fat one, the short, mustached grumpy one, etc.)
Meanwhile, Asians or Polynesians in film still have to be goofballs or non-threatening (meaning no romantic-type) characters.
