"The Americans"

Still fine in season 2, if a little less intense... My interest has been drawn from the complex relationship between the principals (married Russian spies Keri Russell and Matthew Rhys) to the secondary and equally fraught affair between FBI agent Stan (Noah Emmerich) and his Soviet mole (double or triple agent?) Nina (Annet Mahendru). Mahendru is utterly convincing, and Emmerich, with his hang-dog eyes and macho drawl barely concealing his doubts and insecurity, is the most watchable character on TV.
