The direction and non linear way of Nolan is great. Very few directors can make ordinary (yet legendary) story so interesting. Bravo for that. The stories of soldiers in a war. The heroes outside the war. Ones will to survive. How bigger sacrifices change the tide of war. The people who evacuated the 300000 soldiers amidst the attacks. The sound, visuals are good. Historically more accurate as stated by some dunkirk veterans.
