I’m not a fan of war movies but this is amazing. George MacKay finally realises his potential in a deeply affecting, very theatrical WW1 story, apparently adapted from Sam Mendes’ grandfather’s experiences. Incredible performances (including one of Mark Strong’s best) and breathtaking cinematography, with a massively pared down script make this unexpectedly compelling. Held together by MacKay and Dean-Charles Chapman, and frequently told in massively long single takes, it’s a meditation on war with rare integrity. I’ve never seen anything like it.
