Overall this is an excellent movie, I was pleasantly surprised by the alternative approach to a 'war movie' one which slowly builds dread and creates what seems like a genuine example of what war must have felt like. Where it falls short of a higher rating is Nolan's lack of ability to persuade the viewer to invest emotionally into the characters. The vast array of the cast makes it difficult to really feel fear for the survival of the characters because there is no individual protagonist. This is not to take away from the excellent cinematography, acting and the incredible soundtrack masterfully composed by Hans Zimmer, which I can say without a doubt is worthy of an Oscar.
