This we know. Nobody's interested in the narrative. It's a story about an all-powerful thug collecting a half-dozen magic stones — a 160-minute game of rock, rock, rock, rock, rock, rock, scissors, paper. The ridiculous size of the ensemble is the selling point of this film, though after a while, your mind starts to wander back to "Black Panther," which was so satisfying, and fleet of foot, and full of interesting characters. When "Infinity War" relocates to Wakanda, you lean forward a little, only to settle back in your seat again after a few tons of rampant destruction puts a serious dent in the place.
