Fascinating video although it could do with more context - or maybe wanting some context is a tribute to the video.
Just a guy with a video camera but the BBC couldn't do it. The BBC would add context but lose everything else by telling rather than showing. It would tell us about the poignancy instead of allowing us to feel it in our own way - or not feel it at all. The Beeb would probably add some music too - music it just doesn't need.
