Expository Mode
Documentary forefather John Grierson offers an explanation for the move away from poetic documentary, claiming filmmakers, “got caught up in social propaganda …We got on to the social problems of the world, and we ourselves deviated from the poetic line.” (Sussex 1972) The expositional mode diverges sharply from the poetic mode in terms of visual practice and story-telling devices, by virtue of its emphasis on rhetorical content, and its goals of information dissemination or persuasion.
