If you are familiar with the "Tales of Genji", this is pretty much a anime adaption about it. While there is a bit of inaccuracies with it especially in the closing of the anime, certain things hold true such as Genji is playboy from the Heian period and is in love with his stepmother who is technically not that much older than him.
My initial reason for watching this anime was to understand the text form of the story better since reading wasn't always my strong point especially when there are many other classes which had my priority (and the fact that anime was enjoyable). Having watch through the first 5 episodes, I was impressed on how well they kept up with certain facts such as the women he had slept with, the look alike of the women (central theme of the book if you ever read it).
Not much can be said except that I wish they didn't use modern animation to portray a Japanese classic, but rather use something from "Samurai Horror Tales" to make it more nostalgic. It was quite interesting how the anime portray some aspects of it such as evil spirits and some part of Japanese culture during that period.
