Battlestar's Ron Moor has an interview with AMC displaying some nice self-awareness about the extent to which the Final Cylon plot has taken over (and sort of ruined) his show.
Q: The build-up to the final Cylon has been unprecedented. How is the revelation not going to be a letdown?
A: It will never be as powerful as the build-up. I resigned myself to that a long time ago. The "Who Shot JR" of it all is an instructive lesson: No matter who it is, it's still going to be a bit of a letdown. But I decided that precisely because of that, it wasn't going to be in the final episode. I didn't want that to become the entire series. I'm sure there will be a variety of reactions. Some people will love it, some people will hate it. But I think when you see how the revelation fits into the overall mythology of the show, when all the questions are answered by the end, then it'll make sense and you'll think, "Oh, well it kind of had to be that person."
