Alissa Wilkinson reviews the latest Errol Morris Documentary here. This is another in a long line of interview-based films my Morris about divisive political figures (Robert McNamara in “Fog of War” and Rumsfeld in “Unknown Known” among others). While I haven’t gotten a chance to see it, Morris has a propensity to let the powerful talk, to such a degree that they often end up revealing more about themselves then they had intended. I have no doubt this is the same.
