Love this, watched it when I was like 7 and it truly opened my life to African culture.
And the parents' concern about the nudity, I think you are taking it too much out of context, in many cultures the body of women and men are beautiful and quite normal to show it, and nothing to be ashamed of.
When my parent saw the movie with me they explained this cultural difference and it made me understand and respect other cultures and forms of life.
