Took me a while to get round to watching it but I have to say it is nothing short of amazing,I had a full 5 seasons to catch up on and it really has blown me away,love the cast especially the 'big lad' Aidan Dunbar lol it's good to hear loads of old Belfast slang like "do you think i came up the lagan in a bubble" and its good to recognise lots of location scenes from places within a mile of your front door,cant wait to see season 6...full mark's for the writing,screenplay and acting...totally wipes the floor with the American police series's which are like a quick McDonald's compared to a lovely Sunday roast that line of duty serves up...
