Frankly, I was surprised how nondiscriminatory this movie was. Dr. Gazenga was clearly more educated than the rest of the doctors (and more wise than all of the Americans). This is completely unheard of in this day and age; no non-Westerner would be the most intelligent person in the movie. And, for that matter, Dr. Gazenga's comments and practices were to some extent based more on thought (and research into "Jungle Medicine") than archetypal medicine-men.
Disney movies have gone down-hill since this movie, I guess. Instead of glorifying Western society, they diminished it next to more 'primitive' civilizations. I thought this was a highly insightful film.
