Great show and insight into the environment and various animals.
Some people are complaining that production isn't as good as the BBC series, but the same production studio has been used by Netflix for this series. Maybe slightly more polished and when it gets so polished it verges on the edge of looking like CGI, but it still is an amazing viewing experience.
It was meant to be a more serious take on nature and wildlife, with a heavier message than the BBC's nature documentaries of late. You do get a sense of that straight off the bat but I didn't think it was overly pushy, rather just suggesting of finding a balance with nature.
Overall message from this series like many of the others is quite simple....humans are trash ;)
