In addition to the deep-cover family, other characters in the espionage game fill out the cast. An FBI agent lives next door, there are various sources and informants, and several of the Soviet embassy staff become important figures. I enjoyed seeing focus on characters from both sides of the undercover conflict. As you'd expect, there's a high turnover rate...not a safe profession, the spy game.
Spy shenanigans take up about half the plot, and I found most of it to be well written. Sure, you have to suspend your disbelief about the premise of the super-deep-cover setup, and the main characters miraculously survive all kinds of danger on a weekly basis. But that's par for the course on almost any television series. A lot of the spy action is centered around development of personal relationships with individual sources, but there's also plenty of sneaking around and even a few gun battles and car chases.
The time period in the 1980s makes it easier to accept all the disguises and sneaking, although I suppose modern spy thrillers manage the same even in today's cameras-everywhere society. Each season has some kind of big theme for the spying, from stealth aircraft to improved food crops, drawn from the big stories of the time. It was fun to see how the writers worked with the time period, from those significant plot points down to minor references like classic video games.
The other half of the plot comes from all the emotional angst that you'd expect in this kind of situation. Who is sleeping with whom, what lies are being told, the stress of hiding activities from your family and friends, and so on. I found it all interesting at first, though eventually it starts to wear thin. I thought the writers did a pretty good job of showing how the stress of the spy lifestyle wears people down over time, but in so doing there's a ton of repetition.
After about three seasons, I was more than ready for the Jennings family to finally move on from spies to whatever was next, good or bad. I'd kind of hoped that would happen in the fourth or fifth season, but instead it just dragged on in more or less the same vein. Some significant changes did finally happen throughout the final sixth season, which was the best since the first in my opinion. The last episode leaves a lot of loose ends, but there was enough resolved to make it a good series finale.
I'm glad to have watched The Americans, though I think they let it go on too long. If they'd wrapped it up around 4 seasons, that would have been about perfect.
