b.j. bullert, in his book "public television: politics and the battle over documentary film" protested what he viewed as censorship. he stated that dark circle was outside of the mainstream at that time but now the viewpoint in the movie is widely accepted. nat katzman, former kqed station manager, disagreed. he is quoted in bullert's book, saying "it's more difficult to say ("dark circle") falsified anything, but it left one with the uncomfortable feeling that this is propaganda, not journalism".
