Planet Earth II (2017)

This BBC nature documentary is a sequel to the 2006 series called Planet Earth, which according to the BBC has been viewed by 500 million people. The new Planet Earth II series is comprised of six episodes. It debuted in the UK in November 2016, then in the US in February 2017. The six episodes, each of which is one hour long, feature Islands, Mountains, Jungles, Deserts, Grasslands, and Cities (and the animal life that has adapted to urban environments). There's also a seventh "compilation episode" called World of Wonder. Thanks to the BBC Natural History Unit, and the advances in camera technology and techniques, this is about as good as it gets. Can you name any other title that has a 100% rating on the Tomatometer?! NOTE: Planet Earth II should not be confused with the similar sounding BBC series called Blue Planet II (2018), which itself is a sequel to the original Blue Planet of 2001. It too has seven episodes, all of which are about the oceans. Both series are narrated by Sir David Attenborough.
