What this movie lacks is a story, a dramatization, in other words a script. It is not enough to put together a couple of classical anti-war scenes that we have already seen in scores of movies (like for example when a grenade hits and instantly amputates both of a soldier's legs, reminiscent of Black Hawk down), add to that some clichéd soldier behavior (very similar to Jarhead and other movies) and expect this to make for a good film. As a result we couldn't care less what happens to any of the protagonists, we do not have a sense of what is happening on the battlefield and why (even if one knows his history) and we are left empty when the movie finally ends.
On a more positive note, what really is excellent in this movie is the cinematography (reminds me very much of David Lean) and sound (the artillery barrages really sound convincing). This alone however is nowhere nearly enough to elevate this movie to anything but below average.
