Critic Reviews

Attenborough matches the natural world’s grandeur with his own intellectual and moral seriousness.

With Sir David as our guide, it’s a theme well worth plunging into.

Ardent lovers may well wish for someone to look at them the way Attenborough looks at giant kelp; at another moment, he excitedly recalls forgetting to breathe during his first snorkel.

This cracking campaigning documentary makes a galvanising case for action – and without lobbing its audience overboard with an anchor weight of hopelessness yoked to their heels.
