First time I saw this film, I was nearly thirty. Up until then I had always thought Rambo was this typical mainstream, all-muscles-no-brain kind of explosion-action flick, where Stallone shirtless showed all kinds of muscles while ripping throats open and killing whole armies alone with his bare hands.
It is safe to say I was surprised.
Mainly by the depth in the Rambo character. That guy has issues, and Stallone really proved himself as an actor portraying this.
