IF you had said a few years ago that the nation would be gripped by a natural history programme fronted by a 91 year-old we would have laughed.

Yet, Blue Planet II and its presenter Sir David Attenborough is fascinating millions of viewers each Sunday evening. The velvety tones of Britain’s favourite naturalist explain the wonders of land and sea, accompanying the most amazing footage ever of wildlife.

From the tiniest of sea creatures to the largest of those on land, Sir David happily guides us through Nature’s wonders.

The individual stories of how they lure their prey, eat and live is so far away from the usual TV fare of reality shows and trivia as it’s possible to be.

Yet, we just love it. We gasp at the unusual and strange, giggle at creatures’ antics and are touched by nature’s cruelties.

If ever there was an argument for educating the nation via TV this is it.

And we are all happy to call it entertainment of the best kind.
