I think the only interesting thing about this might be what they decide to do about the supernatural stuff. If they change it around to Christianity and use some of the nastier non-canon books of the bible (gospel of Judas, anyone?) they could do some pretty interesting stuff with the aesthetics and art direction. But eh, if they just go for a 1:1 adaption then whatever. I doubt they do a better job than the anime, and the supernatural stuff will get lost in translation and just be super hokey. I'll probably pass on it.
