I enjoyed the first season's worth of episodes of Blood+ but it kinda dragged on and got boring after that for me. I still watched the entire series but it was a bit of a let down overall.
I recently watched DeathNote, freakin' awesome by the way. The first half is better then the second half but overall it's a great anime. I recently started through the Samurai Champloo series again. Oh and I watch Invader Zim a couple of weeks ago too.
