The Great Wall, as we learn from this flick from director Zhang Yimou, was not actually built to keep the Mongolians out of China. Instead, it was made to help fend off alien attackers. This leaves a special group of warriors (led by a mercenary played by Matt Damon) to team up and prevent great destruction at all costs. If this sounds inane to you, don’t worry, because you’re instincts are probably very sharp, as that’s pretty much how critics are responding. Zhang Yimou (House of Flying Daggers – 80%, Hero – 95%) has long been known for making beautiful films, and critics think the visuals are fine enough, but the story reportedly comes up more than a little lacking.
