In recent years American tv shows have been so popular in Iran. Friends, Lost, 24, Prison Break and Heroes are the most successful ones which you can easily find full series of them all over the Persian web-space. But Mad Men hasn't been a popular one yet, and I guess it'll be more famous here in coming years. I like the atmosphere of the show - set in 1960s New York, stories of a group of men who work in an advertising agency - and the characters. Of course the 1st season didn't make me a fan, but watching season 2 - which finished today - was a exciting experience. Both of seasons have been awarded in Golden Globes as the best drama show, and no doubt it'll be more seasons coming.
So if you're looking for a good tv show and interested in Kennedy/Nixon's age, I strongly recommend you to watch Mad Men.
My favorite characters are Don, his wife and Joan. And I really hate Peggy and Campbell!
