It's semi-short. You could most likely get it done with in a weekend or so, But it's extremely good. And for fans of the series, They are releasing the 2nd season I'm guessing with a new cast except the butler looks to be the same. But The GazettE are doing the opening theme song for it. It's going to be out July 07 in Japan, hopefully people sub it right away. Anyway here is a run down on the first season.

"Main article: List of Black Butler characters
In a manor house on the outskirts of Victorian era London, butler Sebastian Michaelis serves Ciel Phantomhive, the twelve-year-old head of an English noble family and a toy and candy empire, who serves directly under the Queen. Sebastian carries out any task required by his master while solving the problems plaguing England with ease and perfection, because of his demonic lineage and Faustian contract with his master."
