Why 5 stars? Because after 100 years of American propaganda films, we finally get to see ONE that has a different perspective. Ever notice that there are no American movies about the Korean war? Its because Hollywood did not have the permission to make them.
This movie is brutal to watch, but that is war. Soldiers injured don't heal in 10 minutes like American movies. The whole undertone of the movie is "war is bad", and "fight for future peace". These are all things prohibited by the American Military Industrial Complex in Hollywood movies. America's forever wars make the same propaganda movies over and over and over.
Want to see a real war movie and not Hollywood BS? Watch this one!
