The movie reviews about the movie can be seen in the comments. What I want to discuss here is the establishment of sky city and dungeon
Watched a series of survival films, including but not limited to Wandering Earth, Doomsday Survival, Snowpiercer, The Day After Tomorrow, Doomsday Collapse, A Quiet Place, Blindfolded, etc. I can't help but think about a question, if the doomsday is really coming, should we prepare refuge places in advance, such as dungeons, sky cities (hanging cities), Noah's Ark or something! Planning for a rainy day?
Can a real sky city be built using maglev technology? Avoid volcanoes, earthquakes, floods, etc. Or dungeons, complete medical treatment, food circulation chain, ecological chain, etc., to avoid meteorite impact, although the probability is small, it does not rule out the possibility.
