Rambo apart from being a great action flick for it's time, also had some very serious undertones about the Vietnam War and the damage it caused those who fought it.
Rambo was walking down the and he was hungry and some Redneck Sheriff too big for his own boots infringed Rambo's rights.
Rambo fought back, he was then tormented and borderline tortured by the Deputies, once again his rights were infringed.
He escapes (illegal custody) and then he is hunted like a criminal, all because he stood up to a bully.
The thing about the movie for me was the way we treated our Vietnam vets, Governments including Australia took 18 y.o men (who were just finding their feet in the world and not old enough to vote let alone drink), trained them to kill mercilessly, has them do just that and then when the war was over threw them back into society with virtually no debrief or rehabilitation and expected them to just simply get on with life.
But all said and done Rambo FUBAR'd he ultimately did not do what he was trained to do .. Kill.
The movie for me showed us in the military at the time the mistakes we made in that era and to some extent we have learned from it.
Things have improved since those days but there is still a long way to go, ask any Vet and he will tell you.
This is why it is so important to support our Troops no matter your country but support them not only while they are "in country" but support them when they get home by getting the systems and supports in place for their re-assimilation back into civilian life.
In Australia the organization is the R.S.L (Returned Serviceman's League)
