Nonfiction filmmaking comes in many forms. Among the hottest documentaries each year are films that expose a hidden story about a cover-up or other wrongdoing, seeking to inspire change by gaining publicity and exposure. They are important and worthwhile, and very often controversial. Equally valid are documentaries that dramatize events in a way meant purely to tell a story rather than to achieve an objective, presenting as clear-cut and straightforward examination using archive footage and interviews. This is one genre that comes closer to being objective than any other.
