Our neighbors recommended us TV series
"The Americans" as a drama about Soviet spy couple that struggles with their marriage.
Surprisingly, "The Americans" plot looks more realistic than I initially thought it would be.
Even most actors who play Soviet spies - speak pure Russian.
(Unfortunately,
the main couple cannot really speak Russian anywhere close to being realistic for the native speakers, but they almost always speak English anyway).
Blood, dirt, sex, cynicism, and passion on both ends of the battle.
I binge watched the first season in a day and now in the second season territory.
"The Americans" is available on Amazon Prime.
