The first scene in Saving Private Ryan was realistic. Everything after it was very unrealistic, with experienced German troops running into gunfire in the open like lemmings. I remember one veteran who was angry because it insulted both armies - it made the Germans look incompetant when they weren't, which in turn trivialised the incredible effort it took to defeat them.
Actually, I have to admit that I haven't seen that film and know little about it. I tried to dig up the exact quote from "This Film Is Not yet Rated" but couldn't find it, so I may have misremembered it.
But the underlying point still stands, even if that film is not a great example. Depictions of war should probably be treated be differently than the kind of over-the-top violence in most action movies that I can only describe as fantasy. Yet the ratings board seems not to take that into account, and just counts splatters of blood in a way that's taken out of context.
