The series is already renewed for a second season, although Fincher hasn’t said much about that yet. He did say that, for him, the best scripts leave clues along the way the lead up to an inevitable ending. Like in Seven, the finale of a story should leave the viewer feeling like there was no other possible place to go.
"It makes a bigger sense at the end," Fincher noted. It’s something to keep in mind as you binge through the first set of episodes, which the director said showcase "good, clean, wholesome, family values."
And, of course, blame Fincher if you can’t sleep at night thinking of killers like Ed Kemper.
