This film is suffers from one major flaw and that is that the genuine horror of being at war and living in a trench is far more frightening than any ghosts or monsters. This would have been a better film if it had lost the supernatural element and had the characters going mad because of the fear of dying and the living conditions they had to cope with. But don't get me wrong, I liked this film, I just feel there is an even better one waiting to be made.
