I am not really much of a war movie fan. However, I married my ex within a year after he returned home from Viet Nam, as he was stationed there for about a year. Needless to say, he and then I took a particular interest in movies about Viet Nam, especially with the memory so fresh in his mind. Man, he sure had a few interesting stories.
Although I can't say we've discussed Nam lately, I do remember him favoring and/or relating to Apocolypse Now, which I'd have to say is probably my favorite, although I've not seen some of the more recent ones.
No one has mentioned "Coming Home", which although years since I've seen it, sure captured the atmosphere of that era and the turmoil and affect this war had on those who served and their loved ones.
