I find Murder City a very refreshing take on a crime drama. Right now, we have 3 different CSI's, among about 10 other crime shows on television at any given night, I have a hard time telling them apart. I agree that the interesting chemistry the lead characters have, not romantic, just that they really work well together, and it is actually believable that they would be working cases together.
Also, kudos to Kris Marshall, I am a huge fan of his work, My Family is on of my very favorite shows, when I saw that he was staring in this series, I knew I had to check it out. Now I'm hooked.
I love this 'smart' approach to a crime drama!!
