One of the best police procedurals I've seen
This series is beautifully written, beautifully acted, beautifully directed, and beautifully shot. And, as others have mentioned, it has a wonderful cast.
It is surely one of the best police procedurals I've ever seen. The storytelling is beautifully done — and all without a lot of gratuitously graphic violence. Most of all, however, the story has a caring heart at its center, without being maudlin. That's what sets it apart, I think.
It was especially enjoyable to watch Sir Tom Courtenay's performance. Brilliant!
