Vietnam movies were usually either about POW experiences or about the absolute pointlessness of it all, which doesn’t really line up with “bombing your country and then making movies about how sad it made them”
I have literally never seen a depiction of Vietnam that was positive or shy of direct condemnation of how terrible it all was.
Seriously, even Forrest Gump’s innocent portrayal of it still managed to underline in bold that it was all pointless, needless, and cruel beyond reason.
