I haven't really kept up with the past several seasons. Frankly, I stopped really paying attention to anime around 2006 or 2007, whichever year had a shit-tonne of overrated vampire-related shows. The only exceptions were during my brief stay in COREA when I was watching Saki and Zetsubou Sensei.

With that said, I am watching Bakemonogatari for the first time. It's a lot stranger than I thought, but I also find the similarity in style to Zetsubou Sensei to be interesting.
