I've been watching some shows a friend recommended to me - Rozen Maiden and DearS
Rozen Maiden really surprised me, I had seen art from the show and heard people mention it, but I never really paid any attention to it. But it turned out to be a great show, so what if it's about dolls... they're badass dolls.

I got hooked on this one, finished watching both seasons and the OVA in less than a week.
DearS... well, it's total fanservice and probably an otaku dream show.

But I loved the humor and it's a very nicely made series, only downer is that the manga wasn't fully animated, so there's a lot more to the story that I don't know.
I really want to watch the second season of Fist of the North Star next, I plowed through 109 episodes to finish the first season in a real short amount of time because I was just hooked on it. I just had to take a break to watch something different.
EDIT: Moel, that avatar is hilarious. Haha!
