I don't know if the reason why in my opinion this 1st episode is far better than "Islands" of Planet Earth 2016 or the later it is the less the animals numbers are but this is the truth. This "From Pole to Pole" episode proves that the quality of the serie is fair to the rate from Imdb. I love this episode, I love the animals, especially the music, I have one thing to say about the music: Awesome. The music is so good that I can see a dust and a very ordinary bug is still so beautiful!
