There was a lot going on in these two episodes, and I'm still kind of processing it, but my first thought is: what a perfect ending. I loved every minute of this. Here you have a rare example of a show that started out pretty middling but somehow just kept getting better and better every season. This final season is easily in top 3 shows of 2017 for me (the other two being The Leftovers and Twin Peaks, just don't ask me to try and rank them), and I'm going to miss it.
