This ethnography is a common one for Anthropology teachers to use as examples. Mine used it as an experiment. Between his two classes he changed the way it was read the first class read an article about Chagnon's methodology before reading the book, the second class (which I was a part of) read the book first and then the article. He did this to see if the students overall view of the book would change. Having finished the book, prior to reading the article, he asked my class how we felt about it. We gave it mostly positive reviews due to Chagnon's great organization of evidence. Then he had us read the article and asked us again how we felt. Most of us had changed our minds because of what we learned. Chagnon may be good at presenting his evidence, but it is important to remember that most of it is considered unreliable by the anthropological community due to his methods. He violated the anthropologists code of ethics many times during this study. Plus he's an asshole, so there's that.
