Cadi's world - and the world around her - is changed forever. Written by AnonymousB

Ignore the bad reviews
20 July 2018 | by bobou-513-708245See all my reviews

Frankly, I don't understand why this is getting bad reviews. I too, watch a lot of British drama, and although the pacing is a little slower than most, it's an extremely well-done series. It does start out slowly, but by the third episode I was totally invested in the story and the characters. The photography and set design was superb, as was the setting. But what I found most compeling was how natural and real the actors all seemed. Everyone seemed to fit their roles perfectly and the lead actress who plays the lead detective is a joy to watch.

Don't pass this one by. No, it's not frenetic. But it has a rare depth and realism that makes it even more enjoyable.
