I'm a fan of British police dramas; I wanted something low-key & interesting. Lloyd & Hill fit the bill. Philip Glenister (Life on Mars & Ashes to Ashes) is a favorite so that's why I chose this. I was pleasantly pleased to find John Light from Father Brown & the familiar face of Shaun Dingwall also in the cast.
If you want intense, this isn't for you; but the "who done it?" aspect kept me unsure until the end. Not super obviously nor something from left field but a very watchable crime drama.
Character development may seem a bit flat, but sometimes the drama between characters can detract from a good story. And it's obvious that this was a potential for a series with the opportunity to fill out both Lloyd & Hill as well as the supporting cast. Alas, that wasn't done.
Recommend.
