Comment on "Through Navajo Eyes"

The part in the book that stood out to me the most was when the navajo elder Sam asked, "Will making movies do my sheep harm " and asked if it would do them any good. He was answered that nothing would happen to the sheeps and then he asks why make movies then? Sam did not even have sheeps at his place but the question he asked raises an important question that all film makers should ask themselves. How does film effect the filmmaker, the ones in the film and the viewers? When making a film it should make an impact not just aesthetically pleasing.
