This series is not light, it's heavy, there is pretty much no comic relief... The acting is excellent, the story-lines often gut wrenching reflecting on the real trials of being human, making bad mistakes and the like. It sounds like a downer, and it might be for some. I watched this for the first time on flix a couple of years ago, and basically binged through both seasons. Saw it again this year, and it's still completely riveting. If you are looking for a "cozy BBC mystery" like Miss Marple this isn't it.
