So refreshing to watch a show where the police are so much more than bland stereotypes; they have depth, emotion, diligence, conviction and most of all empathy. The writing and acting are superb, and the plots are tightly constructed to keep you guessing until the last. IMHO Series 3 was the best so far, but all three series are up there with the best dramas you can find. Must-watch, you won’t regret it.
