There's a fascinating and incredibly timely documentary making the rounds right now. My Perestroika follows five Moscow children from youth to middle age. Straightforward enough, except that they were in their political years (college-aged) as the Iron Curtain came down.
As a child during the final years of the Cold War, I always heard the Soviets needed to change. Because of home video in this documentary, it ends up young Soviet children thought the same of me.
Once the Wall comes down, you see how quickly the five central characters lose the euphoria of a new political system. The producers probably didn't have a hand in the Arab Spring, but you can imagine them rooting it on.
Here's the trailer.
