Gankutsuou is based off the story, The Count of Monte Cristo.
I haven't read the original novel, but I loved Gankutsuou. How close to the original are the plot line and characters?
Was it a faithful rendition or was there some artistic license, because there were several scenes which, to me at least, seemed at odds with a book that would have been written in 1884. (Mostly futuristic elements)
