In “The Flowers of War,’’ when a lone Chinese sniper blows up himself and a pack of Japanese soldiers, the blast sends dust, debris, and fabric flying through the air. It’s not that you notice the colors of the fabric - they’re like fireworks. It’s that you notice that you’ve noticed. The comely images in this movie - and there are many of them - call attention to themselves, as do most of the images in most movies by Zhang Yimou, - from “Ju Dou’’ to “The House of Flying Daggers.’’ The idea here is to foster visual irony. The film is set during World War II not long after the Japanese have devastated the former Chinese capital, Nanking, in 1937 and ’38. Hundreds of thousands of Chinese civilians were murdered, and Japanese battalions stuck around to pick from the massacre’s bones. In many cases, that involved raping girls, young women, and men.
