Ever since his first bigger movies here in Germany (Goodbye Lenin!) I always had an issue with him, something subconcious that I really don't like... can't pinpoint it down, but it went through the roof with Inglourious Basterds and manifested itself with interviews and him being a guest in various talk shows here etc. Just a general dislike for the guy.
Here, with Zemo (and to some extent The Alienist) on the other hand I enjoy his role for the first time and I wholeheartedly agree with you. I find the whole Cold War aesthetic of the show quite fascinating, but they don't land it for me, yet Zemo was great in this episode. But I don't want to be too negative here, I'm just wondering how opinions can differ so much eventhough I enjoy the MCU as much as the next guy.
And yes, I share your sentiments with the power broker.
