Zodiac
"Robert, the Rick Marshalls of the world will suck you dry. They're blind alleys"
Watching this story unfold, not only the story of the actual zodiac killer, but also Robert Graysmith and Paul Avery, was fascinating. The conclusion of the story where they talk out the timeline of the zodiac killer and how it aligns with the time Arthur Leigh Allen spent in prison was so satisfying. I loved the moment where Robert Graysmith found Arthur Leigh Allen and just stared him in the eyes, not so subtly saying he knows who he really is.
Man the tension of when Graysmith is in Vaughn's house, and also when an unknown person enters his house was insane
