During the Q&A after the screening, producer Warren Littlefield said part of the idea of both the film and the show is to demonstrate the best of who we are and the worst of who we are. In the actions of Malvo and Lester, this episode had a lot of the worst, but it also had Molly. We'll find out next week which side of humanity wins, or if it winds up as more of a stalemate (say, with Lester going to jail while Malvo slips away into the night).
Also, I asked Hawley if there was anything he felt comfortable telling the audience about the finale. His response:
"Hold onto your butts."
Oh, boy.
