"You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. All these are the beginning of birth pains."
-- Jesus to His disciples (Matthew 24:6)
Needless to say, there is gratuitous violence in Rambo IV. These are some of the most explosive bullets I have ever heard of... arms, legs and heads flying everywhere.
Yet, somehow, Rambo IV didn't seem excessively unrealistic. The movie was ridiculous, yet not in a bad way. War is ridiculous. We can look back on history and see that war is sometimes necessary, at least from a defensive point of view. But it's still ridiculous.
Just before he goes and takes out an entire battalion of Burmese soldier almost by himself, Rambo says to himself, "You know what you are. What you're made of. War is in your blood. Don't fight it. You didn't kill for your country. You killed for yourself. God's never gonna make that go away. When you're pushed, killing's as easy as breathing."
Rambo IV was written and directed by Sylvester Stallone.
