"Dunkirk" is a special movie. It is not a war movie in the usual sense. You can't see the plots that are common in war movies, such as life and death, political games, and war. Love, etc. Its focus is on "the feeling of war" and "the feelings of people in war".
In this movie, everyone’s feelings are watched and magnified repeatedly. Tommy and his comrades carried the wounded soldiers across the long beach and along the plank road with only one plank left. They crowded onto the ship before the ship weighed anchor. The whole process was slow and stagnant.
This is why Nolan said: ""Dunkirk" is a movie about rhythm and rhythm. 'Sheppard Tone' can produce high and low sounds through the processing of several different sound waves when they are superimposed. Spiral effect. My script is based on this principle. The narrative of the three timelines continues to generate continuous intensity, and the intensity will become stronger and stronger. I don’t want to tell the story through dialogue. It is to promote the audience’s audio-visual experience through images, music and sound effects.”
The entire movie reaches the extreme of emotion in one tense passage after another.
