Having read the existing reviews, I assumed that this was a story that had been told over and over again - Young white girls are feeling better by visiting Africa. *This is bad*.
And yes, it is, but it has delved into this issue a lot deeper than I expected from a product of the current USA culture wars.
These three episodes attempt (which is more than can be said for a lot of documentaries) to explain its subjects from a number of points of view.
Yes, it is about Africa, and it (without my personal experience) seems to represent its reality, and the reality of the people who live and work there reasonably well.
Yes, it's about US Christianity, and (maybe) presents the (in fairness) admirable traits that drive these missionaries to go to these countries that they have literally no clue about, other than the certain knowledge that the countries are in trouble and need help.
But what are these unspecial, unskilled, people really supposed to be doing (other than evangelising) in a country they know (literally) less than nothing about?
Yes, it is about how countries and cultures view each other (in general terms). If that doesn't interest you, skip it. If you appreciate that we live in an unequal world, but also that we are all humans dealing with global problems, then it is worth a watch (IMHO)
