"Compared to fiction films, documentaries must work with the material that presents itself because the environment cannot becom pletely controlled by the film maker. Documentary makers must come face-to-face with problems of morality, fairness, and justice," says Huang. Some people charge that "documentary films are always left-wing; they are by nature a call to arms."
「紀錄片比劇情片有更多的控訴，是因為所面對的世界，不被創作者全面操控，拿攝影機就必須面對更多的道德性思考、對公正公義的辯論」，黃建業說，甚至有人認為，「紀錄片永遠是左派，它是一種標語性語言」。
