There's no other film like this. The idea behind it is taking the viewer through five different scenarios, all leading to the very last day on Earth for humans. One of them is a joke, although the whole film is based on that unique possibility. It's a masterpiece of ingenuity and craft. Four scenarios are scientifically presented by real scientists. That's the scary part of it. But the production quality and the stories used to explain each possible outcome are brilliant. If this short made it, many years ago, to the big screen, I'm sure audiences would've been discussing these things today really seriously. We're in a pandemic. We don't want to be isolated. This film will wake you out of your state of mind, whatever it is. A must watch.
