I went into “12 Strong” (2018) knowing it was “based on a true story” and I have been on this Earth long enough to be highly familiar with the true story of U.S. involvement in Afghanistan. I decided I’d view this film as I would a John Wayne World War II movie. That was a smart move, as the film turned out to be a fine John Wayne flick for the 21st century, mixing melodrama and bluster with radar-guided bombs and sniper rifles. And, of course, the Americans always hit what they’re shooting at and (almost) never get hit themselves.
