From me and all my other otaku buddies to this thread: *GLOMPERS*
YYH is among our top favorite animes, but of course, as mentioned before, the spiritual aspects aren't parallel with our beliefs, but they weren't mean't to be the focal point of the show.
Also, concerning the dub, I've seen a lot of the uncut and as for the cut version, I don't think it's appropriate for kids, 'cause the violence is still pretty intense and then there's Kurama's: "Voyeurism is not my strength" in one of the episodes. (Don't look that word up)
But anyways, love the series and how it can be sad but randomly gets funny. When I inform Laruda on how to navigate this site, you'll be hearing lots from her.
And on a side note, for this year's A-kon, Laruda, Hiei's Girl, Badtz Maru, and I are cosplaying as the four main characters!
