I've been a devoted follower of AMC's The Killing and the nuanced characterization of the effect on the family of a viction. Llast night's season finale was extremely frustrating. I had every expectation that the murderer of Rosie Larsen would be revealed, and - SPOILER ALERT -- although I had my suspicions that it wouldn't be Richmond (mainly because everything pointed to him in the next to last episode, and it seemed unlikely that they would devote an entire previous episode to the "how" of catching him), I was okay with Richmond being the murderer.
But the last minute reveal that Holder was a dirty cop?
Talk about foul play.
