Saw this film last night and was very impressed with its realism.
Very goof filming and infused soundtrack, as well acting.
It gives a very accurate representation of what it was like in the trenches of WW1.
The only part that I thought was a bit weak was the trip mine that went off in the German underground bunker, That explosion would made those guys deaf for at least an hour or more and the large rocks that landed on the guy that was buried, didn't hurt him physically but only a bit of dust in his eyes.
