The guy who made this series of programmes, (this being the first) also made an excellent series of programmes about todays Royal Marines. It focused on people but also the challenges they encountered in the quest for the Green Beret. He also followed them in Afghanistan.
Incidentally the guy at the age of 55 went on to win the much coveted Green Beret. How many of us could even contemplate doing that?
I get the comparisons with that 1970, Sailor and the sentimentality that goes with it, but we are 50 years on, and by the way why not make serious judgements as the series moves along.
