The premise sounded attractive as it followed on the heels of Americans, Homeland etc., but there are three major problems with this one. First, the plots are rather phony and go through rather predictable loops of shifting suspicion from one person to another just to stretch out the episodes. Second, the show - both in terms of acting and directing feels more like a daytime soap opera rather than a suspense/spy thriller. Third, there are too many characters - most of them rather poorly developed. Yet, if you are bored while waiting for the next season of Americans/Homeland/etc., this can be a filler that you can glance at occasionally while reading a book (you wont miss much - coz the storyline is pretty slow).
