There's a lot going on here. It probably isn't nearly what many viewers were thinking it might, or even should, be. I'm guessing many of us expected a raid on this sheriff and his unredeemable contingent of followers getting pretty violent. That would entertain a lot of viewers I'm sure. What we got is a raid that worked less spectacularly with the perpetrator in prison. A raid done well. It set up the ending that had a message. Love and forgiveness is the only way to live without fear. Dot had to do some work to get to that point, she survived as a result. That result is bigger than her, which the ending claims with just a facial expression by Olah. Now, that mother-in-law. That's not quite as neat.
