What do you think is the best Vietnam war film?

I'm just in love with Full Metal Jacket. Particulary and in contrast to the majority of people (i think), i just love the second half of the film. Don't get me wrong Hartman is a pleasurr to watch, espacially with a dub like the italian one which is spectacular, but the second part is very underrated imo.
- Excellent choice! I love the 2nd half too, it's my favourite half of the film. The sniper bit I'd sensational

Cliché answer perhaps but I do love Apocalypse Now. Was a very formative movie experience for me.
- It's a classic! What is it you like about it?
  
  I like just about everything about it really. It's beautifully shot, has moments of great humour and moments of great horror, I love the gradually increasing tension of the journey into the jungle and increasing descent into madness and absurdity.
  It's just a great film. I think I prefer the Redux cut but both are good really. The documentary Heart of Darkness about it is also truly amazing.

I'm a huge platoon fan, I just like the story and how Charlie changes. I also thought casualties of war was brilliant but it was too sad for me to watch a 2nd time
- Platoon is my favorite as well. Love the contrasting cultures of the soldiers, think it really reflects where America was at on the war (old school, liquor drinking "patriots" backing violence vs. pot smokers just trying to get home alive). Oliver Stone is also an actual Vietnam vet too, Charlie is basically a self insert if I remember correctly.
