I've heard Stallone interviewed about his last installment in the Rambo series.  I've also read reviews of the film.  Those who saw the film only as an exploitation of gore, would do well to review the stories coming out of Myanmar (Burma).  When asked why there, why put Rambo there, his response was simple,

"I called Soldier of Fortune magazine and they said Burma was the foremost area of human abuse on the planet," Stallone said.

Stallone is now editing John Rambo, which will be released in January, and said he is trying to strike a balance and grapple with the question, "Are you making a documentary or a Rambo movie?"

I wish that I could tell all my lib friends that armies and police forces are unnecessary, but evidence throughout the world (including within the US) would indicate that they are and that the reason that they are necessary is to provide for civil behavior.  Humans do not behave well.

Sly, in part, made the movie to point out the silly hypocrasy of thinking that we rid the world of one man bin Ladin or Hussain or even Hitler, and there will never be another to take their place... t'ain't so... There will always be an evil personification who for whatever reason sees him/herself above the other members of the human race - and subjugates others to incredible suffering and torture.

in short, I think that if Sly were to die right now, this film would be his contribution to society... it is not pretty - nor is it comforting...  it does however, portray one aspect of the "human condition"
