Expository
A very traditional form of documentary in which an unseen speaker performs a voiceover commentary that literally explains the images that we are seeing. It is the form often associated with wild life or historic documentaries, in which the viewer might feel in need of information about what they are seeing. The audience is not particularly ‘empowered’ by this kind of approach, finding itself in a subordinate role listening to the version of events that the filmmakers choose to prioritise.
