its strange that there arnt any american korean war movies

i did watched some great korean war movies from south korea like ''brotherhood of war'' and ''the front line''. however while searching for movies that focus on the american side of the war the only ones i could find are documentaries from the 50's. that is indeed strange because it was a very big war. in fact. alot of the ww2 veterans who fought in the pacific side also fought in the korea war. and the war lasted 3 years and 48,000 american soldiers participated in it. its also was the first war with black soldiers fighting together with whites in the same divisions. i would prefer to see a realistic depiction of that war instead of over-glamorizing movies about ww2. like that average as hell movie
