Love this mystery show. I've never watched the previous iteration or read the books, but I feel that this show follows the feel, spirit, grit, and the time period of the source material. The British and PBS, etc. Are always great at this. Carvel...fantastic..as Dagliesh and as both of his side kicks mention he makes for a great detective and mentor.
But, for me, this show suffers from two issues:
1. It is so dark (visually)!! Seems like they've filmed all the episodes in the middle of a British winter. I live in Santa Fe, NM, (super high altitude sunshine), and I literally have to close all my curtains so I can see what's going on. It was very noticeable in this current episode (a couple of murders in a seminary/church/boys school). In one scene, a protagonist runs by some daffodils. They are so bright they look like they are fake. When the flowers are brought in, they seem to glow, and the entire background fades into grey/black.
2. Dagliesh is so deadpan!!! If there were a drinking game about taking a shot any time anyone in this show smiled or laughed, the bottle would never crack open. OK, so this show is not a funny, laugh-a-minute procedural a la "Murder in Paradise," or "Harry Wild," or "Shakespeare and Hathaway," but even the darker show, "Vera," has a handful of laughs and smiles per episode.
