OK this is just a beautiful piece of television. Packed with fascinating history, geography and zoology. Told with great enthusiasm by excellent presenters. Nick Crane is just superb. His account of the French 'invasion' of a corner of Wales (in Napoleonic times) had me in stitches.
Neil Oliver, too, has the courage to be rather patriotic, which doesn't seem to be fashionable amongst many educators these days - and I like him for it. I disagree with the reviewer who finds too much emphasis on WW2 (this appears again in series 5 actually). These parts of the programme are particularly fascinating, but really there's a very broad range of historical material presented. There's much on the history of science and invention, for example, which I find riveting. Alice Roberts helps a team building a replica stone-age dwelling, crawls into ancient mines, and changes hair-colour from time to time...
Time and again, the presenters manage to make some part of the coastline seem like one of the most important places in our history. The programmes bear watching over and over, there's just so much (quite scholarly) knowledge in them.
I can't praise the makers of this series enough. Inspiring work.
