Caught this flick the other day. It reminded me very strongly of Fog of War, one of my favorite films of all time. It's probably the most impressive interview "get" I've ever heard of—all six of the former heads of the Israeli intelligence service talk with astonishing bluntness about their careers and the state of Israel vis-a-vis the Palestinians and Arab neighbors.
Imagine David Petraeus and his five predecessors talking like Nation columnists and you'll have some idea.
It's a bit slow, especially at first, and also entirely in Hebrew, but incredibly interesting. Very highly recommended.
