Is a movie bad because it tells you what you already know? Let me re-phrase that. Is a movie that wants to say something important bad because…? War is bad. We can all agree on that. No-one would disagree with a movie being anti-war (unless it was a bad anti-war movie). But does the world need another movie that tells us war is bad (like it was saying something new)? In the Valley of Elah is well-made, well-acted and well-short of insight into warfare. It thinks the Iraq war is something new; that what happens in Baghdad is somehow different from Stalingrad; Nanking; the Somme.
