I was a bit late in watching this having started on series 2. I managed to catch up on series 1 later on Netflix to give me the background.
I must say that each series has been well written and good to see that along with Keeley Hawes there was also Daniel Mays from A2A. I think Danny Mays is an excellent actor that I would have liked to have had more involvement in Line Of Duty.
I'm going to say this once and once only Gene: Stay out of Camberwick Green!
Hell. I think age ratings are a bit different to what they used to be. This is only a 15 - as, to my amazement, is Happy Valley. God knows what you'd have to put in a police drama to make it an 18.
Plenty of T&A, gory violence and lots of swearing, including f-words. Murphy's Law should have been an 18 as that had some very disturbing and brutal moments. Quite an old show, but it was tough as hell and James Nesbitt gave a gritty, hard-boiled turn.
