Hard to fault, watched the series twice even though I have pretty good recall of each episode. Nicola Walker and Sanjeev Bhaskar so believable as real people working out their work and their lives, both with complications. Performance, ensemble like. A nuanced story again reflective of reality rather good v evil in black and white. Nicola Walker - I'm a fan and have been for a while, Sanjeev, amazingly talented, that switch between comedy to the other side of human emotion and shades in between. Casting was brilliant and Nicola and Sanjeev was a real coup. Magic and believable together. Can't wait for S4.
