I'm not a big fan of political intrigues and whatnot, but the solid team of producers, writers, directors and actors made me think this was going to be good.
And it is. Solid script, neat acting and storytelling. Love the production design too. London looks more beautiful than it actually is, at least in my own experience
We do care about the "ambassador" Kate, struggling to balance what she must do (moving to the UK on a seemingly PR gig) vs what she would like to do (going on the ground the middle east). She's the "good cop", noble intents and so on, while her husband might be the "bad cop" conspiring with different characters.
It's a lot of fun, edited quickly and in a meaningful way. Really solid show. It's the first time after I dont even know how long that the ending really surprises me.
Main issue, at least in this first episode: too many characters show up for a brief moment: complicated job titles and hierarchical procedures do not help. It might be realistic but it soon becomes really confusing. This is the reason for 6/10. You can watch it if you like the genre and clear about all the political forces at play
the negative reviews about her hair changing style are laughable. A door open, close and open again: hence passage of time.
