On a recent flight I saw Charlie Wilson's War, and it brought to the silver screen (or LCD, in this case) a couple of interesting points. We already knew that for the Soviets the invasion of Afghanistan was an equivalent of the Vietnam War for the Americans, but I didn't know that many details (still sketchy, after all, it's only a movie) on the American covert operations there.
The movie is funny and well-paced, but one thing that I would have liked to see more is a better job at bringing home the point that some of the "freedom fighters" of the 80's became the "terrorists" of the 2000's due to neglect.
Interestingly enough, I remember some of the newsclips shown in the film, even though then I was a small kid.
