I'll take a different angle from most of you:
This show isn't good enough to watch without sleuthing.
Seriously, it's so missable. Especially this last season, which was junk. Fleiss even took some of the joy out of the sleuthing by feeding us too much. He forgot the first rule from the first minute from the first class in Storytelling 101: tension creates drama, and without drama, you have no story. He had no tension, no drama, no story in Season 12. It was way over-telegraphed even to people who didn't sleuth. So that took even more fun out of it, and had it not been for the discussions here, there would have been no point in watching, at least in this household.
The move from lurking, which I did for several years, to posting, which I began with Matt's season, made a huge difference, too. It was a net positive, however. Without this site, I have no incentive to make it "appointment television."
So I'm in for Deanna's season. Definitely in.
