Quite good. The Jon Stewart movie reminds me of Alexander Solzhenitsyn's Gulag Archipelago in the way that it examines what our hero, Maziar Bahari (Played by Gael Garcia Bernal) has to go through. The Iranians who imprison Bahari knew that the brutal methods of SAVAK were worthless in obtaining credible confessions. The somewhat surprising twist is that Bahari doesn't hold out 'til the bitter end, never telling his captors what they want to hear. He does, but the world accurately identifies his confession as worthless because it's so obviously obtained under duress.
Very good look at current Iranian society and the relationship between captor and captive and the limits of what societies can do to oppress individuals.
