This documentary stayed with me, not just for the subject matter but for the brilliantly balanced way in which it was done. How does a filmmaker make a documentary about an event to which no one was a witness, and about which everyone has a vastly different opinion? That's not easy, but this film does it beautifully. The animation is lovely and conveys all the emotions of the subject without being shmaltzy. The various opinions are presented sensitively and with equal weight, and the viewer is allowed to make up his own mind. Was John brave or foolish? Was he brainwashed or did he act on his own accord? Does the church have his blood on its hands? Should he be emulated or scorned? Evidence is given for all of those possibilities, but the decision is yours. At the same time, John is never treated like a fool, but is given a lot of respect by the filmmakers for his intelligence, his compassion, and his determination, for better or for worse. We really get to know him through the interviews, his writings, his home movies, and through his friends and family. We can't help but like the guy, and that's an admirable goal achieved by the filmmakers. What is also very rare and startling is the idea of NatGeo turning the microscope on itself, and questioning its own role in how remote "uncivilized" communities were portrayed, and if they as publishers and documentarians share some of the blame for some negative stereotypes. Lastly, I see some of the negative user reviews here and it seems to me most are highly critical of John himself, and therefore of this biography, but that's really short-sighted. The point isn't to rate the film based on how much we love or hate missionaries; I'm chosing to praise the film for the excellent job it does of showing both the extreme zealots and the non-belivers, and several others in between, and letting the viewer make the final call.
