This is a good movie which probably would have been an even better movie if the story had been based on actual facts. The operation to smuggle out the six Americans was primarily a Canadian, not American, action and the lead hero was the Canadian ambassador who protected the Americans and then arranged for them to leave the country. This is not to say that the United States had no role, because it did, but contrary to the movie, it were the Canadians who took the lead. Also, the fact that the American official sent to escort the Americans was Hispanic is not even mentioned, which would have added another dimension to the story. The movie also demonizes the Iranians who are portrayed as little more than uncontrollable rabble, when in fact, what happened in 1979 was the culmination of a long series of grievances harbored by many Iranians against the United States. This does not mean that the Iranians should be excused for what they did when they stormed the embassy, which was a blatant violation of international law governing the protection of embassies, and for which the Iranian government must be held to account, but their actions must be examined within a larger historical and political context, something which the movie to its credit alludes to, but does not incorporate more fully into the story. Ben Affleck gives an excellent performance as the CIA person and the story moves forward at a brisk pace with a lot of tension and excitement; it's a good movie. But it's not a documentary.
