An astonishing achievement. From the first few minutes the confidence and clarity of this film is established. The extraordinary dexterity of the camerawork - all one shot continuous takes - draws the viewer - close - up - into the visceral horror. A roller coaster of a journey through a shell - shocked landscape. A nightmare from which our players cannot wake. Exceptional performances all round with some incisive cameos from Benedict Cumberbach, Colin Firth and Mark Strong, but the film belongs to George Mackay who bears witness to the inhumanity of war. His call to unimaginable heroism, like Odysseus, noble, innocent and brave. A testament of youth. Sam Mendes has made a masterpiece.
