Ranbir,
OK, but let's be practical. Normally, the documentaries and willdife films are made by two kinds of people: a) those who wish to increase visibility as documetarians and are receiving funding for their work and b) those who are doing it to increase awareness and spread the word of wildlife. In this case let's leave out the third faction that does it only for the money.
Actually, both factions are actually bringing out a situation from which the general public can understand what plagues wildlife and get their thought processes going. What we should be worried about in terms of how much a human should penetrate a jungle, is the fact that, increasingly, our wildlife is turning accustomed to human intrusion (tigers, leopards, etc), whereas our elephants are beginning to resent such intrusion. Clearly we are on a collision path, but practically, if none of us watch TV, none of us would know what a tiger looks like in the wild, for the simple fact that we don't have the time, resources to stay for a year in a willdlife reserve to catch a glimpse of the tiger. In both cases we are heading for a severe man-animal conflict. But the upside is that maybe enough people can watch these documentaries and fight for conservation.
You have mentioned the declining numbers of alpha males and their inherited desire to control - this is evolution at work, and cannot be considered unnatural. Our main issue here is whether we can sustain a gene pool in varied habitats.
