The quietness of this movie was an instant reminder that the producers had little idea of the reality of the Western Front. From Flanders to the Swiss border you could - at any time of day or night - always hear the distant booms of artillery barrages.

Also, this movie was so full of 21st-century features - non-white troops embedded with British front-line units and so on - that it's a wonder the producers didn't try to work in a lesbian subplot.

As a piece of fantasy it's not half bad. As a realistic portrayal of the Western Front in the spring of 1917 it's a dud.
