Critic after critic is calling Dunkirk Nolan's masterpiece and best film to date.  I simply can't do that and no filmmaker should ever get a pass.  In fact, it might be the worst of his films I have seen, but that's like slipping from a king-size Sleep Number mattress to a king-size pillowtop mattress.  The fall isn't far.  Allow me to explain.  Here's my "Movie Classroom" interactive whiteboard presentation of the audio form of my written review as it appears posted on Every Movie Has a Lesson's YouTube channel.  Enjoy!
