I have never written any review on movies, web series and documentary in my 38 yrs of life.. Post watching this master piece documentary which illustrate complete journey of the life of all species, I am out of my words. Every human being must watch this and all of us shoud learn rich, poor, religion, caste, color, language, artificial intelligence, big and small are doesn't matter. It's all nature call which decides the life on the earth. On humour part, looks like male species struggled to find their female partner right from the first form of their life billions of years ago while female species njoyed their comfort life. Male never dominated in the history of earth.. So please follow your wife or stay single to reduce human population and let other species thrive to keep the earth alive.
