 In general, documentaries, especially educational documentaries are scripted such that the audience is persuaded to accept a specific lesson or message, the performative mode of documentary is used to break from a monological or monotone understanding not only through the use of dialogical principles of dialogical anthropology, but of experimental ethnography.The Himpele and Castaneda therefore create an ethnographic documentary that expands the idea of experimental ethnography as a set of principles for writing a text to producing and postproducing ethnographic film.In her book Looking Two Ways (1996), Toni de Bromhead criticises Nichols for his focus on documentary as a rational discourse.
