After refusing to go on a dangerous mission in Afghanistan, where people suffer from wars, instability, and corruption, John Rambo, a strong warrior, breaks the rules and stays at his town, but incidents come to climax, when his old friend Trautman has captured, as he has to do his best, in order to rescue him.
Engages the plight of the Mujahideen with a humanizing, doc-like approach (fascinating to witness, all these years later, when the ally/enemy tables have turned so drastically).
Mostly, Rambo III is one breathtaking sequence after another, with an absolutely mind-boggling scene with Rambo removing a spike from his side, and then sealing the wound with flaming gunpowder.
It's a very bad film, but now has an interesting element when viewed in retrospect -- Rambo goes to Afghanistan to fight with the Mujaheddin against the Soviets.
Always at ground zero in the chaos is Rambo -- gloriously, inhumanly impervious to fear and danger -- whose character is inhabited by Stallone with messianic intensity.
