Agreed. I think "The Americans" is still at the top of my list for the last decade then it's a tossup between "The Leftovers", "Severance" and "Mr. Robot".
Edit: I forgot "Andor". Easily the best Star Wars thing since the original 3. I like how it shows the hubris and infighting of The Empire and how that leaves openings for the resistance. Feels like a very real look into the workings of an authoritarian regime.
Americans is great-- a little uneven because there is a lot more of it then say, Patriot, but also a typically underrated show. Superb cast (they were actually married) and a great take on the material. They could have made them goodie two shoes who subverted their mission; they could have made them sinister spies. Instead they made them people.
"Or perhaps you find my politics a bit strong for your taste?" was some of the best television I had ever seen in my life, easily up there with the best lines from Breaking Bad or Anthony Hopkins' monologues in West World. The build-up to that moment was masterfully done. I got goosebumps at that crescendo.
Mr. Robot had one of the craziest endings I have ever seen in a show. I'll admit I had a tough time watching it around S2 because so much was unexplained, and I felt like I was going insane.
So glad I stuck it out though, I still think about it.
