The shell-shocked Normandy landing is fantastic. But the knife fight was much more emotional, less brute shock, more person-to-person. The German soldier trying to ease his passing is the human touch that makes it so much more intense.
Full Metal Jacket is my favorite war movie, but Saving Private Ryan is definitely one of my favorites. I'd love to see a decent WWII movie that actually captures the importance of Soviet Russia though. It seems like we Americans brush aside the Soviet role in WWII, it's really quite annoying.
