A film is not only photography and some beautiful footage. With that I do not want to mean we can find this in 1917 at all because it is only a good attempt at photography sometimes but others filmmakers have done much better before. The film is only entertaiment and nothing else. Long time without seeing so many mistakes in a story and in what any normal human behaviour would be. For a large list I would have to write spoilers everywhere. This is the big issue.

A few good actors without any deep lines or chance to pronunce themselves. But it happens so fast that you don't even realize it. It sounds like a few ones maybe realized the bad situation but someone in a hurry said "no way...let´s the war begin".
