Yep read the wiki and it sounds as though it wouldn't be my cup of tea but I'd have to see an episode before I could make up me mind .
Shoot up action is more my kind of thing . Though not always . I liked the Tsubasa Chronicals both series , fairly light hearted . A much darker and slightly intelectual offering is Death Note .
The Rozen Maiden series 1 + 2 are meant to be for kids . Kids in Japan are pretty wierd if thats the case
those dolls were just plain spooky .
