It is one of the very few movies be it animated or live action that I know of with an ugly, old ( and awesome ) female main character and one who gets a romance with a gorgeous male too! :)
I don't really consider Sophie to be " ugly " per se even though she DID have low self-esteem even before she was cursed by the witch and turned into an old lady but she DOES spend most of the movie as an old lady and Howl falls in love with her knowing fully well that he may never see her as a young lady again and he still loves her despite her old and objectively ugly appearance which is something very rare to see in romance movies...
Plus even if you're not interested in the romance part the movie is still a lot of fun like Studio Ghibli movies tend to be! :)
