Black Butler stylishly blends fantasy with horror, comedy with action... the characters in the show are its major strong point. The protagonist is a cynical, dark little boy with a sharp wit and deep intellect who is assisted by his butler, who seems to be able to do anything - because he really can do anything, seeing as he's demonic. It is disturbing yet quite entertaining all at once.
Some great points about this show are: the comedic side characters, such as the incompetent house keepers who manage to do the exact opposite of what their jobs require; the twist on history by including major murders/criminal events in the storyline, like the Jack the Ripper scandal; and the old English and Victorian soundtrack and clothing for the characters.
*TL;DR Version*: For viewers interested in the supernatural and the occult without needing a huge amount of violence or heaviness this is the perfect series to watch. The concept of selling your soul to the devil to get what you desire or need is re-explored, when in this case, the devil actually comes to the protagonist's aid as the household help.
OVERALL: 9/10 :)
