Before this decade, the idea that great directors would work on the small screen seemed extremely unlikely. TV's small budgets and episodic nature didn't seem like a good combination for creative exploration, but the industry changed. And with those changes, came Mindhunter. David Fincher's methodical and perfectionist show about a group of FBI agents interviewing serial killers builds tension masterfully, turning simple conversations into nail-biting vignettes that haunt viewers long after they are finished. Based on real-life events and criminals, Mindhunter is chilling without being exploitative.
