yeah, Disney get's a lot of bad rap on it's princesses but the deserve more respect. there actualy symbols of great responcibality, but critics are to buisy judging them for being pretty. Anyways. normaly they stay a princess when they take over a kingdom, butif they are the official ruler then they are realy a queen.
Queens get an even worse Rap, and not all queens are evil villians you know. so maybe seeing a good princess become a queen may help shift the balance of opinions and give Disney princesses the respect they truly earned after all these years.
