Dominic West is brilliant in this
Just rewatched this again on Netflix and Dominic is just sooo *beep* good. I've been a big fan of his since I first saw The Wire so maybe I'm a little biased.
The scene that really impressed me was the one after they were digging for Fred's first wife out in the field and it was night time outside the police station. When West broke down to Janet about Anne Mcfall and hugged her. He was just so desperate and had a million emotions going in a billion different directions and Dominic just nailed it.
