Cameron Britton is going to win an Emmy for his performance.
One of may favorite scenes is when we get a glimpse at the BTK killer, who isn't explicitly identified throughout the entire series, as he waits in a house by himself waiting for a victim and then leaves angrily when nobody shows up.
The backstory of this true occurrence is incredible. The victim in this case was an old woman the BTK killer had been stalking for days, and somehow by sheer chance she evaded being murdered several times by staying out late or deciding not to go home at the last second.
He eventually gave up and later told investigators that her evasion absolutely infuriated him beyond belief. Once she was told how close she was to death the old woman promptly moved out of state.
What an awesome part of that awful timeline to put in the show.
