Movie Critique/Review
As previously mentioned, at the outset the movie rather “dises” the British, while praising Canada (but it doesn't at all explain why the British couldn't offer shelter to the six).
As should be expected since it is based upon the memories of the exfiltrator it is weak on the actions of Canadian Diplomats in Tehran.
Perhaps most annoying is part of the last six minutes where after one CIA Officer says “Thank God for Canada”; the follow-up line should have been “in addition to all they have actually done for us, we have to be sure that the Agency's involvement isn't mentioned at all since it would endanger the lives of the hostages.” Instead as delivered it sounds like sour grapes, and frankly should have been re-shot (it would have been less than a minute and a half).
It also "disses" Antonio Mendez the CIA Officer, in-fact he was painting (fine art not house painting) at home when he was called into the office, in the movie he is separated and it looks like he has been on a Chinese take-out and beer bender in a hotel room.
Would be interested in learning how much of the story Ambassador and Mrs. Taylor's housekeeper is factual.
Now as to the Movie as a movie
It has humour and lots of dramatic tension, in general it is a decent movie and certainly I'd recommend seeming it.
