Nolan has taken the conventions of the war picture, its reliance on multiple protagonists, grand maneuvers, and parallel and converging lines of action, and subjected it to the sort of experimentation characteristic of art cinema. . . . Nolan exploits one feature of crosscutting: that it often runs its strands of action at different rates. . . . As a sort of cinematic tesseract, Dunkirk is an imaginative, engrossing effort to innovate within the bounds of Hollywood's storytelling tradition.
