Ok,
I have just watched the original "First Blood" from 1982 again, for the 1st time in like about 10 years & it got me to thinking how Hollywood ended up skewing the original message intended by the 1st movie, by making all the sequels.
The 1st one was clearly meant to depict how hard life was for the Vietnam Vets, whom had come home & how they faced difficulty adjusting to Civillian life. The whole message behind the movie is summed up beautifukky in Stallones performance at the end, where Col. Troutman is trying to calm him down. This scene dramatically, I believe communicates the anguish these guys went through.
The part where Hollywood screwed up though, was all the destruction & action scenes. Whether they intended to, or not, that touched off a public demand for more of the same & soon you had your Rambo's 2, 3 & Die Hards etc...so while Hollywood got big $$$ from the spin-off effect. I believe that it only distracts from the original, which was more like a Docu-Drama, with lots of explosions.
