I've been thoroughly enjoying this dark gritty drama. All the leads are excellent, but Sarah Lancashire as the main police officer with a tragic family history, is outstanding. It started well then just got better and better with each episode and twist of the plot (and screw) having me on the edge of my seat. I've just watched what must be the penultimate episode and it has left me physically shaking - it was that convincing and shocking. It's hard to credit the complaint of mumbling by one reviewer. I can't recall even one line of script I didn't follow and it's usually something that bugs me. I'm so glad I've watched this series, it's got to be one of (if not the) best TV dramas of 2014.
