I think if you can believe a soldier would open up an M60 machine gun on the public okay, then throughout film he's carrying the belts of blanks over his shoulders, knives to throats , randomly blowing up supplies and weapons, carrying a dead body through a swamp whilst being pursued by armed men , whilst in America. Deliverance was a simpler more believable, better acted film imo. That said there's probably loads of 80s films I shouldn't rewatch lol.
