A. O. Scott of "The New York Times" called it "exacting, enraging" and said "Ferguson presents familiar material with impressive concision and impact, offering a clear, temperate and devastating account of high-level arrogance and incompetence." Scott said "most of the movie deals with a period of a few months in the spring and summer of 2003, when a series of decisions were made that did much to determine the terrible course of subsequent events" and wrote "the knowledge and expertise of military, diplomatic and technical professionals was overridden by the ideological certainty of political loyalists." Scott also remarked, "It might be argued that since Mr. Bremer, Mr. Rumsfeld and Mr. Wolfowitz declined to appear in the film, Mr. Ferguson was able to present only one side of the story. But the accumulated professional standing of the people he did interview, and their calm, detailed insistence on the facts, makes such an objection implausible." Scott concluded, "It’s a sober, revelatory and absolutely vital film."
