I really enjoyed it. But it left me a bit empty. My take away from it, was that the real 'bad people' (MI6) are so embedded and protected that their work is not going to stop just because the more public/exposed figures (Laurie's character) are removed. Olivia Colman's character essentially accomplished nothing and was after the wrong people the entire time.
