Is Moana just the same old princess?

I have been paying so much more attention to Disney in media and news, but now that I'm looking, I feel like it isn't showing up as much.  So, I asked a group of my friends to let me know if they ever come across anything interesting with Disney.  One of them pulled through (shout-out to the wonderful Grace), referring me to a Snapchat Discovery feed that contained a post titled, "Will Moana Really Be Different From Other Disney Princesses?"  It is one of the first things I read about Moana (trailer) and I am now very curious to see it when it hits the theatres on November 23rd.  The short article pondered if Moana's body type will be different enough from the classic Barbie-doll figure of the other Disney princesses.  Moana looks like an athletic and fit young woman, and still extremely skinny.  I think Moana is a great step toward varying the image of a princess or desirable body figure.  Also from the article, I learned that Moana will not have a love interest.  Since all (most?) other princess movies revolve around the man, I am looking forward to see what Disney does with the plot of this movie.  The article also referred to the complaints of people over the depiction of the Polynesian demigod, saying that it creates a negative stereotype.  After a little research, Maui seems like he is supposed to be a large, strong man, and that is exactly what his character looks like.  Maybe his character will even help with the perception of large people, showing that big is not equivalent to unhealthy, out of shape, or lazy.
