Doesn't America or Canada have shelters? There are a couple of strange decisions in this movie, but... the one that basically keeps lingering...
Why on earth does one flee from upstate New York to try to reach a shelter in Greenland? It is closer to Europe where the big one would hit. Now, I am a European, and in Hollywood Europe is often to go first. I would have understood that you'd fly to Greenland if the big one was going to hit in the USA, but okay.
All other goofs and mistakes have been commented on, but I missed this one in them.
All in all a decent movie, good pace, keeping you on your toes, but I often thought "Oh, common. Get real."
I would have felt ripped off after seeing this in the theaters, but seeing this on Netflix in the afternoon free time... the only thing I really lost was "time." No biggy 😊
