I'll have to add Tai guk ki (A brother's war) for its' non-stop action, The beast and 9th rota/Company. I don't know if somebody had platoon, we were soldiers and other great 'Nam movies in here but I'll add them.
Passchendaele was so terrible, and I wanted to loooooove it so much being Canadian and it being a major Canadian war film, but the director ruined it for me with the shameless gratification of only his grandfather at points and the terrible, half-assed, hour-long love story put in to attempt to appease the women in the audience. I'll be the unbiased arbiter from the country of the production's creation and take it out of the running unless there's someone from Terriblelovesidestori(a/stan).
