If I have to pick between two Vietnam films, I would have to say The Deer Hunter.
A much more emotional explosive movie. Small town U.S.A, with a group of young naive men ready to fight the evil of communism.
How all three men were so different and how the war affected them very differently.
From the scene with the Russian roulette to them coming home back to Pennsylvania to face their friends and loved ones. This is very powerful & emotional stuff.
I will have to say this is the greatest and most powerful war movie to date!
