This movie has everything going for it - great acting, directing, suspense, and humor to go along with a lot more. Ben Affleck has proven again that he is a top notch filmmaker with an eye for great drama. I even think his performances have improved over his earlier work since he's stepped behind the camera to take on directing duties.
With this movie, he takes on a real life event and puts the audience smack dab in the middle of it. It seems you're right there in the room when Iranians storm the American Embassy in the the late 1970s, you feel the angst as you escape with six Americans and hide out at the Canadian Ambassador's house, and you're right there with the CIA trying to figure out how to get those six out of Iran. John Goodman and Alan Arkin provide the humor, the operation of extracting the trapped Americans provides the suspense, and Ben Affleck is terrific as the man behind the camera and as the character risking his life to make sure the operation succeeds. Bryan Cranston also deserves a shoutout as Affleck's boss who delivers some great lines and scenes in the movie as well.
From the 70s feel to the movie, to the great performances by everyone involved, to Affleck's great leadership behind the camera - Argo has plenty to offer audiences who enjoy good humor and great suspense. It's one of the best movies I've seen this year.
