Watch Homo Sapiens Full Movie Free Online 123Movies. HOMO SAPIENS is visionary documentarian Nikolaus Geyrhalter's exploration of the finiteness and fragility of human existence, the end of the industrial age, and what it means to be a human being. What will remain of our lives after we're gone? Empty spaces, ruins, cities, increasingly overgrown with vegetation, crumbling asphalt: the areas we currently inhabit, now abandoned and decaying, gradually reclaimed by nature. Comprised of a succession of eerily depopulated, dystopian landscapes from across the world, HOMO SAPIENS offers an at once mesmerizing and chilling vision of what a posthuman future might look like.
