This was breathtaking TV, crafted by the best mammals in the business: us humans, led by a certain tireless nonagenarian.

The relish with which Attenborough described his subjects was palpable, from his delighted emphasis on the “hairy” armadillo to the exotic lilt he afforded the word “gerbil”. The stories may have been epic, but the success of their telling was all in the details.

With Mammals, [Attenborough] adds another triumph to his peerless legacy, investigating the myriad ways in which mammals strive to survive and thrive on this ever-changing planet.

Thrilling, illuminating, unnerving, Mammals delivers yet another precious helping of high-grade natural history. Attenborough business as usual.

Mammals might be wide in its scope but so far it is unerringly hunting down marvels.
