Parents need to know that this dark political thriller maintains a mysterious, foreboding tone that may unsettle sensitive viewers. Several violent incidents occur throughout the series, including murders, but many of these events are filmed from a distance. And the camera doesn't linger on victims or gore, focusing on evoking psychological tension more than visual shock. Several characters drink and smoke obsessively. Some scenes show people who are happily intoxicated, while others involve a bitter alcoholic. Romance is a big part of the series, so kissing, passionate embraces, and occasional references to sex appear. Some war scenes appear, as well as subtle references to gang rape.

Families can talk about the appeal of spy thrillers. Do you think real espionage is as exciting as it is on TV and in the movies? How have technology and the media changed the nature of the spy game? Families can also discuss the Cold War, Russia, and communism. What do parents remember about the Cold War? Teens: What do you know about that period? What kind of connections can you make in your own life to that time? How have politics changed (or not changed) since then?
