The documentary genre aims to document real events using actual footage or reconstruction. While footage may appear untouched, documentaries still involve direction and construction. A good documentary focuses on its topic rather than style of presentation, but needs structure and pacing tools like editing to make the content coherent and engaging. There are five key elements of documentaries: observation, interviews, mise-en-scene, dramatization, and exposition. Different types of documentaries employ varying combinations of these elements through approaches like fully narrated, fly on the wall, mixed, self-reflective, docudrama, and docusoap styles.
