It was really chilling at the beginning but I feel like the creepy vibe just crumbled in on itself once it got to the "all humans are bad" part, like from that point on it just made me shrug because I knew where it was going and I lost interest. It would have been truly horrifying if you showed the good parts of humanity being destroyed along with the earth. But the way it was done it was all kind of... overkill, actually
