“What’s the Matter with Kansas?” is a great episode of The Americans because it’s a weird episode of The Americans.
The weirdness begins with the title. Historically, episodes of The Americans that end in questions marks have performed very well. See the all-time great “Do Mail Robots Dream of Electric Sheep?” That title was, of course, a play on the Philip K. Dick short story that eventually became Total Recall.
