The Abe who worked on Lain and Boogiepop Phantom? I think you'll find his worst show is Dai Shogun.
you need to read the novels first to understand all the lore and the settings of the anime,also the ost, op and ending are really good.
I can only watch an ep every six months or so. I like the atmosphere even if i have no idea whats happening but it's almost painfully slow and the fisheye lens and grain aren't 't helping. Awesome mood though.
