This has got to be one of the dumbest sci-fi movies, behind Armageddon, and slightly forward of Independence Day, with my money on this genre going to Deep Impact for cosmic disaster movies, and "Life," with Rebecca Fergusson as the chair-grabber for alien predation upon the earth.
Moonfall is not fulfilling for the educated or critically thinking viewer. The movie starts fine with alarm over the declining orbit of the moon, but what is soon determined to be alien AI swarming out of a crater like bees, with the moon turning out to be an artificial satellite (about an 8th into the movie), the premise about as firm as the science behind Mothra. Then, Berry and Patrick Wilson somehow resurrecting a derelict, museum-housed space shuttle within a day to launch a mission to save the world ... Well, one has to suspend ALL disbelief, not just nuggets. The movie defies all scientific certainty of what happens when a massive object enters the earth's atmosphere, to include its gravity sucking up buildings and ships, while people just need to 'hang on' to something, or just drive really fast. The animation and CGI were impressive, but unfortunately the only redeeming factor used as weak glue to keep the movie together.
