Blood+

I loved the OP and also Saya and Diva ^ ^

It didn't remain in the mainstream long enough.

I really like it so far, I'm near the end, so it may have "slow" parts but they seem to be important dialog to explain the story, didn't mind it at all.

I hated the anime Blood +. The animation quality was terrible. Fights lasted less than a minute and lacked any real movement. Also this Saya was just a little b*tch that rarely could do anything by herself.

This is an ok anime but I would not recommend it. I thought the main monsters where more like lycans then vampires.
I realy licked the ending. It was pleasantly anti-climatic. :P
