I haven't seen this movie in many years, so my viewing is colored by nostalgia and the intervening years.
I didn't realize how many "jungle war" tropes were in this movie. From the perspective of someone who knows nothing of film history, I would blindly say this movie started a ton of them.
"If it bleeds, we can kill it."
"Come on, kill me, I'm right here!"
"Get to the chopper!"
Classic lines I didn't realize were from Predator.
