To say that The Americans is an underrated show would be an understatement. It takes you back to a world left behind and amazes you with their story telling, acting, drama and wigs....yes, wigs!
The show succeeds to hold your attention well and even when it gets just a little dull you'd notice how good it is in spite of its dull moments. Sex, violence, drama etc is judiciously used with good acting in plenty.
