Just saw this movie today. I have to say it was very good. Now, I am a veteran, but of course I didn't serve in WWI.
Impossible for any of us to truly experience what the WWI soldiers had to experience. However, watching this film, I can say that I believe it accurately depicts the conditions of the trenches, and "no mans land" better than any other WWI film I've seen IMO. It also shows the brutality of war very well.
I won't give away the story, but I will say many left the theatre with watery eyes including my wife and my father.
Good movie, and well worth seeing IMHO.
