Weakest season of all and a big disappointment.
It's like they took what they were known for and turned it up to 11. The pace at its slowest, the backburner at it's slightest, sub-plots the most disconnected they ever were from the main plot.
Somebody explain me the insistence on Burov. A complete misfire. Even heyday Nina and the Residentura didn't get as much screen time as Oleg did this season. It was uninteresting and irrelevant and perplexing. Yes, to the credit of The Americans they tend to stick with characters and follow through with them a lot after they stop being meaningful to the larger story, but this time they took it to new heights. Whatever they wanted to get across, they could have done with much less time and use it on other much-needed areas of the show.
Also, what was the point of Stan learning about Gaad? I thought that finally the Burov thing is starting to matter and that Stan will agree to blackmail Oleg so they can get the people behind Gaad's death. But the thing was never mentioned again and Burov's bore continued on.
What was the point of Mischa finally getting his way to US only to promptly go back because Gabriel said he couldn't see Phillip. Pretty late to start abiding the KGB\s request no? And again, after Gabriel had his change of heart and went back to Russia, i thought, surely, he's going to help Mischa to get to the US again and meet Phillip, But again. Nope. Subverting expectation for subversion's sake. Never mind that is also made a perfect fit for their 3 sons theme (Henry, Tuan and Mischa).
This season made it clear we're following Stan because he's Stan. Not because his line of work or a potential whiff he's going to get on the Jennings. And it's not like what he was doing was riveting. The Stan-parts this season could have heavily benefited from more screen-time (instead of doubling down on Oleg). And again, what was supposed to be a trigger for something (the info on Gaad) amounted to nothing.
I would also have liked to see more 'on the job' time by the Jennings apart from the wheat project. I also feel like they could have given more time to Paige, and Matthew pretty much vanished from existence after the break-up.
Anyhow, bummer. While there continued to be elements of what brought the show acclaim, they were overshadowed by weak subplots and bizarre time allocations and decisions.
Hopefully the last 10 episodes bring it, but i'm not as sure now.
