Thhe essence of documentary filmmaking is how you manipulate the material to create an emotional impact, as opposed to just delivering information.
The power of the documentary film, when done well, I think is usually more impacting than a narrative, at least for me. Documentaries are also cheaper, they are more accessible to make.
The main reason why I'm a documentary filmmaker is the power of the medium. The most powerful films I've seen have been documentaries. Of course, there are some narrative films that I could never forget, but there are more documentaries that have had that impact on me.
