Binged watched series 1-3 on Netflix, bonus no adverts. Why? Because it’s a beautifully crafted series, very well scripted, all characters have depth, it’s meticulously well researched, fantastically well acted, and I always wanted more. The two key characters are very believable, Sunny, for my money, is best actor. Their team is brilliant. Not often we get seriously good scripts from one writer, I’m now ploddingly watching series 4, weekly, on ITV, with blessed adverts..... but I can’t wait.
