Being not too far from finishing Season 1, part of the attraction is that it keeps the viewer constantly guessing what is real and what is not, what has been real at some point and no longer is, what wasn’t and has become thus in the meanwhile.
The writing is hardly perfect, however, and some things may appear paper thin under closer scrutiny.
For much of the season I’ve also had the feeling it’s a show about how hard is making a marriage work, with the counterintelligence seemingly being used as a tool to make this otherwise unattractive topic fancy, and the matter is actually brought up openly on a regular basis.
Also you don’t truly know whether they’re just “virtue signalling”, playing a role (one of many).
Most of the time I am looking intently at Matthew Rhys’s face and wondering what his char is truly feeling or thinking.
Keri’s is depicted as more of a hothead idealist (…of sorts), and that makes Elizabeth look like the puppetmasters/writers are pulling her strings to entertain the viewer, in what feels to me more decidedly overt, while Philip seems more natural.
I also wondered whether Philip is a pathological liar.
