David Hoffman's commentary on prejudice in documentary film making is refreshingly realistic. He doesn't claim that a director can remove bias from a film, but that one needs to be aware of which stereotypes they believe in so that they can set them aside and understand what will provoke thought in an audience.

The editing of his filmed lecture with scenes from Sputnik Mania as well as other media was well done and added to the thought progression, rather than being distracting. Kudos to the editing team.
