Already a critical darling, The Americans just needs to conquer, well, Americans themselves. While the FX series, starring Keri Russell and Matthew Rhys, has drawn positive reviews, it hasn't done quite so well in the ratings – though thankfully, it's been picked up for a third season. Set during the 1980s Cold War, the period drama was created and produced by former CIA agent Joe Weisberg, focusing on two Soviet agents masquerading as a married couple in Washington, D.C. The fast-paced spy-vs-spy thriller will leave you wondering which "Americans" you should root for – the embedded Russians or the born-and-bred FBI spooks in hot pursuit. Nail, meet biting.
