I really love the Americans, it's a great show. I think you can stream the first two seasons on Amazon prime and they're headed into the third week of the new season so you can catch up quick if you wanted to.
Takes place in early 80's DC, Keri Russell and her husband (can't remember the actors name) are Russian spies and they have two kids who are raised here, not knowing who their parents really are. Their neighbor is the CIA agent who is out to catch them. Good mix of family dynamic, espionage, action, sex (it's basically how Keri Russell gets whats she wants out of people) and suspense. There are a few legit "oh ****" moments in each season that kept me watching. Plus they do a really awesome job with the 80's cars, fashion, music and events, like Reagan's assassination attempt.
I know it's old news, but I'm going to try to get through Mad Men again before the last half of the last season starts in April.
