Human Planet

As much as I hate the fact that we're ruining this planet for all the other species (but also ourselves), I must say Human Planet is probably the best of all the nature documentaries. The cinematography is excellent, the stories sublime and so very human, and John Hurt (rest in peace, War Doctor) is an amazing narrator, definitely on par with Attenborough. The "Behind the Lens" segments at the end are especially brilliant.

If you haven't seen Human Planet yet, do so. You won't regret it.
