When the article says:-

  adapted from a Stewart Edward White story [...]
  This one is a dreadfully misogynistic short story, full
  of equally dreadful stereotypes about indigenous people

That's actually the article's author criticising of the original story which was published in 1901, rather than the film adaption

In other words, the article author is saying "The directors could have hewed more closely to the source material, but I can see why they made the decision they made"
