For over 2 hours, this movie shows the first hours and days after the loss of satellite communications on Earth. The result is the collapse of all civilian life within a short time. And just before anarchy takes over, the film ends. But the little girl is happy because she has found what matters the most to her in the bunker and she is safe.
Such an event would not only occur if a hidden enemy caused these things to happen. It is not even clear whether that was the cause in the case of the film. These things can also be caused by cosmic rays, geomagnetic storms and solar flares, which occur regularly. On average, once in less than a millennium. These are known as Miyake events. The last known event that had a significant impact was the Carrington event in 1859.
The consequences of such an event would be far more threatening today than in 1859. It would throw us back to the Stone Age. Such geomagnetic storms destroy electronic circuits, semiconductors etc. This was not an issue back then since these haven't been invented yet. Nowadays it would be a huge problem. The entire planet is in the hands of semiconductors and computers.
Whatever the cause was, the idea of what it would be like if that horror were to happen today is thrilling because it's a real threat.
The actors do a great job - that's not just an empty phrase. The cinematography is great. The CGI is impressive. This movie deserves a rating above 7 stars. I am not sure what causes all of these bad reviews story-wise, and what these people do expect.
The movie's message: what has the modern life made of us? We are focused on technology and ourselves and have lost what makes us human. Perhaps a reset would help, at least in that regard.
