1. Planet Earth II (2016)
It was a battle to the death for the top spot between all the Planet Earths, Blue Planets and Life trilogy. Ultimately, however, the stunning action movie/horror movie scene (you can see why they brought in blockbuster composer Hans Zimmer) of the baby marine iguanas outpacing the racer snakes to the sea edged out the competition and pushed the second instalment over the top. It’s like Charlie Chaplin’s Little Tramp vs Predator. Ten full years after the first Planet Earth series, and the 4k images, movie editing and meticulous storytelling just kept getting better.
