I grew up on John Wayne movies including war movies, and you knew where you stood and be entertained by the grit, blood, and determination to win the wars.  Nowadays all you see is 'political' war movies.

If they can't make a World War 2 Sgt Rock movie as how we know it, then don't make it at all!  Somebody has already said that the nearest we're gonig to get Sgt Rock on the big screen is Band of Brothers, and that is true.
