At the end of each episode there is a short documentary on the difficulty or special technique used to film some of the scenes. In a sense it is interesting to see behind the camera but also slightly unnecessary. Seeing a pack of hunting dogs spreading and ambushing their prey at great speed through rough scrub, clearly requires immense patience, alot of high tech cameras and a helicopter. I didn't think you could do it any other way. Waiting for a snow leopard takes a while, I didn't really need to hear a grumpy camera man telling me that. The rest is absolutely fantastic natural history. Not that Attenborough has ever been associated with anything less. There is fair amount of death in these episodes but it makes one appreciate how easy our lives are, protected from predation in any significant way.
