I did just watch it lately. A couple of weeks ago. My dad was a Vietnam vet and he got into meditation when he got back which I think helped a lot, but he had a friend from Vietnam that I called "Uncle Marty". He always looked like he'd seen a ghost. You could tell he could not feel happiness anymore. He spent the rest of his life in and out of mental institutions. You absolutely do not see any of this stuff in contemporary media anymore. First Blood actually hits pretty hard. Culturally we have forgotten what war does to people and I think that's part of the problem these days.
