84C MoPic was different, saw it back in '89. Apocalypse Now is one of the better Vietnam films but is Coppola's vision of how weird and hallucinogenic the war appeared to him.
After a while all the 'Nam films were so cliche by 1990. They all followed the same recipe....Show some Hueys, add random 1960s song, show guys dressed in jungle fatigues and steel pots with M-16s.
