Query: Very interesting and controversial film

Dr. Schweitzer was certainly a very noble and extraordinary person. As a professional, he has completely dedicated his life to helping others. However, in many ways he sacrificed his family (an ill wife and a young daughter) for the well-being of the world.Doblmeier's film successfully highlights this controversy of Dr. Schweitzer's legacy. I strongly recommend it, especially to those who try to find out the right balance between their professional ambitions and family needs.
