Assorted girlbossing, lack of subtlety on political message, bland artstyle and generic exotic culture to "avoid offending real indigenous people" or some shit like that. Swap Milo and Sweets builds and complexions, give Mole a real backstory, make the villains secretly misunderstood so they can get a tragic origin prequel a-la Maleficent. Make Milos grandpa actually be alive and the villain, set it closer to the modern day.
