The most intense, well written, well acted crime series I've ever seen on television. For six weeks I've been hooked on a story that uses a police drama as a framework for the human emotions that are at the core of this fantastic series. Steve Pemberton (The League of Gentlemen, Inside No 9) as the self-interested accountant out of his depth when a kidnapping plot goes horribly wrong was brilliant and James Norton was easily one of the best psychopaths I've ever seen in a television drama. There was real depth to his character and I expect he was hated by viewers as much as Joffre in Game of Thrones nonsense police officer. But it was Sarah Lancashire's show all the way as the tough, no-nonsense, but damaged police officer. At first I thought this was going to go the way of the film Fargo, with it's kidnapping-gone-wrong scenario, but by the start of the second episode it was clear that it was going to take a different path. Be warned though, it's dark and unsettling with moments of sudden shocking violence, especially at the end of the fourth episode, where I was left shaking at the sheer intensity of it all. Better than anything American crime dramas have had to offer us over the past year, it was brilliant. Absolutely bloody brilliant!
