Really loved this series. Idris is exceptional as always. My negative (which is why there are 8 stars and not 10!) is that it could have been 10 episodes. The last episode and a half, a lot happened. There could have been a bit more at the end (although not crucial as it keeps you thinking) but definitely felt like the last hour and a half were rushed and could have been extended. Excellent series. Could extend to a new series with a different negotiation story... Would recommend regardless. This is a great story, well played, well acted. Twists and turns. Great views of London and surrounds. Well played.
