This interesting article discusses the increasing tendency of wildlife filmakers not to strictly observe nature, but to enhance and sensationalize it either through their narrative style or technical means.
"film-makers seem to be drifting towards a kind of biophobia, towards ever more reductionist points of view, more anthropocentric stagings, more aggressive and invasive filming techniques."
Rather than bringing us closer to understanding the other species on this planet, they are, in effect, making them more foreign.
