I thought it was pretty meh. Warming Glow had a very different take:
‘The Americans’ Second Season Finale Recap: Simple, Unexpected, PerfectSeason two of FX’s The Americans wrapped up last night with “The Echo,” and it did so in a way that was so typical of the understated series: It was both completely unexpected, and yet, it made total sense. I think that, because of the nature of the show, because of its darkness, and its thematic complexity, we often expect deeper conspiracies are at play, but once we cut through the clutter, the storylines are often fairly simple and, as they did last night, wrap up neatly. The decisions that the characters make are not simple, of course, but the consequences are.
Take for instance, Stan Beeman, who spent much of the season agonizing over whether he would betray his mistress Nina, or if he would betray his country by spilling secrets to the KGB to protect her. There was a lot going on in that subplot, particularly on Nina’s side, because it was hard to tell what her true feelings were, especially once Oleg and her became involved. What became apparent in the end was that both Oleg and Stan loved her, but while Oleg was willing to risk his own ###, give Nina a stack of cash, and tell her to run, Stan ultimately didn’t love Nina enough. He chose country over love, left Nina a note, and the consequences were fairly simple: Nina would be taken back to Russia, tried for treason, and possibly executed (I’d like to think that she will ultimately be spared because I really like the character, but I do think that that particular subplot with Stan has been played out now. If Nina ultimately survives, both her and Stan need to move on to different storylines).
