I watched this with a roommate who was a former Marine and I remember he was sitting on a couch behind me and toward the end when it gets sad nothing but sniffeling was coming out. The movie end neither one of look at each other and go to our rooms.
The Elephant Man (out of my latest suggestions this one got me the most).
Terms of Endearment
Steel Magnolias
Mice of Men
Hotel Rwanda
Leaving Las Vegas
Speaking of the war movies add Platoon and The Pianist!!!
The scene at the end when the father falls in the puddle trying to catch up to son and and he can't get up and the family is standing around him really got me.
