This is a very emotionless film. It is constructed on silence and cinematography and lacks a storyline or character building. At some point I started feeling as if I am watching a documentary on WWII... the problem is it was simply boring and not engaging . It relied heavily on sound. At points can be impressive but sometimes just loud and annoying. What can I say? War sucks. If someone would go to the bathroom and return and ask "what have I missed " during the film, I would say "nothing". You've missed nothing. Nolan is known to be bad at character writing, his characters are very one dimensional or at least many times it comes off as such, though not everyone will agree with me on this one. People admire his films which lack depth simply because they are confused with grandiose cinematic experience. This is really exceptional though, that he managed to make an entire film without even one substantial character that we care about. I can see what he tried to do here, to create the fear and horrors of the war, what it is actually like. But it is just boring without a background story. Sorry Nolan! Fail!
