Our Planet II is chock full of spectacular scenes of animals on the move, but it also shows us things we might not have known about the whys and hows of how certain species migrate.

Creatures great and small get their chance to shine in the spotlight, to have each little feather, strand of fur, or bug in their eye magnified for us to study. The visuals are stunning.

Our Planet is spectacular to look at and conveys its vital message with telling examples, however depressing. I would sooner re-watch Planet Earth, but Attenborough is still Attenborough: one of the most vital forces on TV.

Take a step back and so much of Our Planet II is astonishing.
