Well a German princess should be blond and pudgy, dancing a polka and wearing braids by the standards everybody is using. I just looked up the plot and having a Robin hood as the male star is stupid. So no wonder the movie is a bomb.
German women are good looking and the princess has black hair and pure white skin, this princess looks Hispanic and while doable, she does not amaze with beauty and vie as the most beautiful woman in the Kingdom against a beautiful Queen, in fact, in this movie the Queen is prettier than the Hispanic girl.
