Same here. I think the only time that hasn't quite worked for me was when it came to Stan's reaction to the death of Amador. I get that Amador was his partner, and any of their number being killed by the KGB would make them all angry, but Stan made it seem like his feelings were personal, and I never got from what went before that he felt like that about Amador.

However, that's not so much a failure of the show to provide a consistent narrative, I suppose. More a failure of the actors. At least in my personal perception. It may well have worked fine for others.
