The first issue I have is with set design, the movie posits the trenches as a bit muddy but not too bad. The plot ambles from device to device to keep it moving but I was more and more incredulous the longer it went on. The 'single' shot was impressive and immersive but let down by the wider portrayal of the action. Many critical reviews have made the same observations I would so I won't labour the points, but it reflects badly on the other offerings we've had this year that this film has got the accolades that it has.
