I was very impressed and touched by the movie, for me its the most accurate movie about WW I so far. I had no problems of following the plot. For me it was a very good movie, which delivered its core message, that the individual counts nothing in the horrors of a modern war, he's nothing more than a resource like grenades, tanks, flame throwers and there is no heroism in death on battlefield.
And for me there was a huge disconnect between common soldier, while the first eats wet bread and plunders the conquered enemy trench, the second one is feeding his dog with uneaten quails.
