Much of the HUMINT (that is human intelligence not signal/cyber/military/etc.) nowadays resembles what is actually depicted here. Even if 'boosted' a bit for flair the script seems far more anchored in reality than American agency themed dazzling action pop shows. The story will be fascinating to viewers partly for the stark difference, in many ways the show seems to be looking back at the superb "Tinker, Taylor, Soldier, Spy" of 1979 rather than trying to copy the pyrotechnics of a "Mission Impossible" modern franchise.
The acting is overall competent and delivers professionally scenes that are believable with a good interaction and no low points. Photography is sometimes excessively bleak but is consistent and sometimes inspired. I would desaturate a bit less, but hey... it has a defined taste at least. Editing and directing are up to the tasks at hand.
The series has no technical major flaws and even if the very beginning promised a bit faster plot, in the second year it has found its own pace which is slow and safe while constantly entertaining.
The Romeo Section has only one thing cutting it short of its achievable 8/10: "Rufus" played by Juan Riedinger. Even if he's not a terrible actor his mediocre performance coupled with a boring character and unimpressive, predictable story line is a real disservice to the whole. The need for that part of the story to be good for the total narrative to work is real, so it should have been better written and casted properly.
