Documentary films are nonfiction motion pictures intended to document aspects of reality primarily for instruction or maintaining historical records. Social media platforms have allowed documentaries to improve distribution and education reach. Documentaries can be used for journalism, advocacy, or personal expression. They aim to entertain, educate, persuade and inform, with values of being educative, illuminating issues, and engaging empathy. A good documentary raises questions, uses impartial filmmaking, and constructs a particular vision of reality through techniques to inform, convince and persuade.
