Im hard to pleas and i want to know some really good english dubed anime shows?

Have you tried Higurashi no Naku Koro ni and Umineko no Naku Koro ni(sequel)? I'm not sure if they have English dubs or not. They do have subs, though. Another good show is Madoka Magica, but I don't think there's really a lot of blood in there. Again, don't know if there's an English dub, but there are subs. As for shows similar to Black Butler, I would recommend Gosick. This show is also about solving mysteries and also takes place in the Victorian times. D. Gray-Man is also good, but I've never watched the anime—only the manga. The manga is about exorcists who use their innocence to fight beasts called akuma and try to take down Millenium Earl, the one who creates these beasts. There's an average amount of blood in the manga. Plenty of action scenes and comedy scenes.
