This is a tale of a Soldiers struggle to keep a promise. It is a visual masterpiece but it lacks in believability. As a Soldier parts of the tale did not make any sense but I take it with a grain of salt as it is based in World War 1. It delivers action and suspense while draped in the hellish emotions of a world falling apart around our protagonist. If you didn't catch in on the big screen, it's worth the rental or watching it on TV.
