Based on a true story, this manages to balance the surreal, dry humor of the paper itself, with the story of the paper itself - how it was produced and how it attracted opprobium from the top brass - and also the WWI experience of an officer in the trenches, dealing with the men, the war, and the conditions. The humor for me was more clever than laugh out loud, but is excellently observed. The characters are well sketched and excellently acted. And the extracts from the paper itself are illuminating, in terms of what they reveal about the soldiers (or at least the officers) and their view of the war.
