This document discusses different types of documentaries: fully narrated documentaries which use voiceovers to guide viewers; fly on the wall documentaries which use little commentary to give an observational view; self-reflexive documentaries where filmmakers talk directly to viewers; docu-dramas which reenact real events through dramatization; and docu-soaps which follow groups of people in an observational style. Each type has strengths and weaknesses in how they inform or engage audiences.
