The plot is a simple one - 2 guys have to deliver a message to the battalion stationed on the other side. What makes this an wonderful experience rather than a 'see and forget' movie is the exceptional cinematography by Roger Deakins. The entire movie looks like a single shot and it makes you feel you are walking along with the 2 protagonists rather than watching it. There are good jump scare moments in the film. Overall, a wonderful experience this movie is!!
