“The Great Wall” adopts a philosophy that all famous wonders must be rooted in the legend of absurdist yarns, and that their endurance apparently comes at the expense of sacrifices too great for the respect of modern civilization. Of course, no one involved contemplates the scientific practicality of that suggestion, but no wonder – movies of this vain are far more devoted to their underlying cynicism than they are focused on creating believable worlds, even in the context of their rather elastic suggestions. But for the sake of getting through a basic plot description, let us suspend, for a brief minute, the disbelief that comes when we contemplate this ridiculous premise. Thousands of years ago, China’s great wall was constructed as a barrier to keep enemies away from the empire they hoped to dismantle, but the greatest of those threats was not human at all: it was a horde of ravenous beasts resembling alligators on stilts, who moved with ferocious speed, attacked with evolving precision and seemed to feed from the psychic energy of a queen who, I guess, desired to conquer all mankind in some karma-ridden crusade. The human characters regard this war with military precision and unsmiling focus (as they should), but it never dawns on anyone involved that maybe, just maybe, a future that must be saved from the dangers of an alien reptile onslaught may not be a future worth facing in the first place.
