I have just started 2009 anime Genji Monogatari Sennenki, an 11-ep adaptation of the famous "Tale of Genji", arguably the earliest novel ever written, following the endless quest for love and entertainment of Hikaru Genji, a prince in 11th-century Japan.
I checked it out for two reasons:
* I plan to read the very lengthy novel but an anime focusing on a few incidents in the story is an accessible way to delve into the world prior to reading it so I won't be lost entirely
* The artwork is insanely gorgeous.
After an episode in, I love it - the artwork is amazing and the leisurely, looping, melancholy narrative is an art in and of itself. It's all pervaded by equal parts beauty, longing, and loss.
