A few points to consider. The two men sent on the mission looked overfed, flabby and unfit. When do generals discuss the content of military messages with the messengers? The "finds bucket of milk and then later finds hungry baby in an active war zone" part was laughable. A pilot is shot down in a dog fight and is badly injured and on fire. He is rescued by two men. They try to tend to the wounded pilot but he stabs and kills one of his rescuer, which almost always happens. There are no large waterfalls in the battlefield areas of Flanders Finally, the way the soldiers spoke was more 2017 then 1917, particularly the senior officers. Completely inauthentic and typical of crass modern film making. At least they didn't make the two messengers gay!
