For police procedurals, Line of Duty, is the top of the heap. And this recent season on Britbox is a doozy of thrills, surprises and fully developed character anti-heroes. Adrian Dunbar gives his best performance in the series as the beleaguered Superintendent along with the charismatic leads Martin Compston and Vicky Mcclure. Yes it is confusing even if you’ve watched the previous five seasons. But it’s a rollercoaster entertainment ride that will keep you edgy during the seven brilliant episodes.
