Personally, I'm STILL pissed off at them for not just keeping all 12 cylon models as "normal" skin-job cylons. I hated the idea that there are these five "special" cylons, and I hate it even more that there is an even SPECIALER 12th/5th cylon. Fucking ridiculous. I also feel like this whole thing has created lots of unnecessary retcon, especially when rewatching the earlier seasons. UGH.
