Long in the making, the idea behind the show was to, using some cutting-edge technology, film previously unseen areas of the ocean, and to investigate life beneath the waves. And in doing so, it pretty much encompasses the full spectrum of creature size. From the staggering, gigantic whale of the first episode, through the miniscule life that’s documented as the programme progresses, it’s a jaw-dropping experience.

It’s also a very, very accessible one. Thanks to a diligent, warm narrative from Sir David Attenborough, there’s plenty of fact married up to the sheer spectacle of The Blue Planet, although in many ways the stunning photography almost needs no accompaniment. It’s timeless work, too, with immense rewatch value, uncovering both life that’s never been photographed previously while charting the habits of the more familiar. Icing The Blue Planet’s cake is a series of short pieces documenting just how some of the incredible pictures were captured, and these are almost as interesting as the main feature.

Enough of those superlatives, though. Because The Blue Planet simply demands to be seen and enjoyed. Prepare, like many before you, to be mesmerised. --Simon Brew
