On an IMAX screen this looks formidable and all-immersive as we follow three timelines leading up to the evacuations of British soldiers from Dunkirk during the early years of WWII. It opens with a spectacular shot of pamphlets falling from the sky letting the soldiers know that they are surrounded. That’s all we need to know. It ends with another great shot of a plane gently gliding and landing on a beach…yes this was made for a huge screen and it is worth it. We have a soldier on the beach, a fighter pilot providing some air cover in amazing dogfights and a small boat with a father and his son heading to help with the evacuations. War really sucks and we feel it in every moment here. Dialogue is sparse and the plot is very simple. The Germans bomb the beach, sink the ships from the air and from u-boats and there seems to be no way off.
