And you can probably preserve those IQ points by just not paying too much attention to what there is of a plot or to some weird elements like the unnecessary reference to “our friends at SpaceX” and a character wondering “What would Elon do?” There’s an endorsement of religion, perhaps to counter a plot turn that undermines some core beliefs of some faiths. A moment that is supposed to be tender and heartwarming as characters reconcile in the face of mass extermination is awkward and random. And the movie does not seem to know how to make the most of genuine big movie star and brilliant actress Halle Berry, stuck much of the time with exposition, cheering other characters on, and wrinkling her lovely brow to show concern.

This is one of those movies where a “fringe” (other people might use the word “crackpot”) “scientist” (not if your definition includes peer review) is the only person who has figured out that the moon is hollow because it is mechanical, constructed, as in not natural. That is space-obsessed KC Houseman (John Bradley), who has a cat named Fuzz Aldren, an English accent, and a tiny following in conspiracy-minded corners of the internet.

What the actual scientists have begun to figure out, and which KC believes confirms his theories, is that the moon’s orbit is shifting and this is deeply concerning because it moderates our home planet’s wobble on its axis, leading to a relatively stable climate and causes the tides. So if it gets out of whack, even a little, it affects everything on earth, from our days and months to our oceans. And if it gets too much out of whack, it collides with us, causing massive tsunamis and earthquakes and ultimately killing everyone. Furthermore, “city-sized pieces of moon debris” hitting the earth could destroy everything.

In other words, it’s a big deal and someone better figure out a way to stop it. In other other words, this is basically “Don’t Look Up” without the satire. That means that most of the people in any kind of position of power either lie (nice cameo by Donald Sutherland who wisely says his lines and gets out), dither around, throw nuclear missiles at everything or or duck out. Most of the people not in power descend into “everyone for himself” chaos. So only our scrappy little group working outside the system can save the day. They do accept help, though, from techies, scientists, and the military.

That team consists of our fringe “scientist,” and astronauts Jo (Halle Berry) and Brian (Patrick Wilson), one the closest of colleagues but estranged for ten years following a failed mission where their colleague was killed. We go back and forth between their mission to somehow knock the moon back on course and the perils faced by their children trying to get to Colorado, which for some reason has been picked as a safe place. That’s Brian’s college-age son (Charlie Plummer) with his mother, her Lexus-dealer second husband (Michael Pena) and their young daughters and Jo’s young son and his nanny. I did enjoy the Roche limit developments that took advantage of the gravitational changes as the moon approached earth.

The sketchy storyline borrows shamelessly from “Superman,” “Battleship Earth,” and “Contact” without adding anything new. Explosion movies don’t need to be smart but they shouldn’t be this dumb. “Everything we thought we knew about the universe is out the window,” a character says. Maybe they should have thrown this script out of the window at the same time.

Parents should know that this film has end-of-the-world scenes of massive natural and un-natural disasters, guns, suicide, looting, sad deaths including a parent who sacrifices himself to save his child, a handful of bad words, marijuana and medication.
