well, Kenshin, I would say is worth a look but I would personally suggest you keep understanding of what your watching, they have a series of eps in the 3rd Arch of the show dealing with someone who thinks he is God basically... this strand can be taken as symbolic, Christian-mocking, or neither. It all depends on how you personally view it, also, near the very end of the show, their is a Feng Shui (I hope that is spelled right) ep line which I
seriously did not enjoy. I think it is worth it, the best of it is the second arch IMO, than 1st, than 3rd. Forgive me if any of this seemed spoiler-ish to you, I tried not to be exact. But I would say however, if you see it, don't watch the dub, download them on the web or something, or rent the DVDs, the dub is...ok... for the most part, but a character from the second arch called Sojiro has a VERY ANNOYING DUB VOICE and can't pronounce the names well FOR BEANS...
InuYasha is my all-time favorite anime, just after seeing the first 3 episodes of it (plus I saw a few dub on adult swim), there is alot of eastern religion, and stuff like soul stealing, reincarnation, and false 'gods' (for example around ep 27 has a 'water god'). The translation as demon, is not accurate, they are actually beast-like mythical creatures called Youkai, not demons, the villains in the show are EXTREMELY creepy at times, but that doesn't bother me because evil is not a pretty sight, and because of the freakish appearances I find it more symbolic. They have awesome character development in this show, and they have done several things I never would have seen coming. I was hooked right away and they show has not lost its pace. My end opinion, I would watch carefully, but I
would however, watch. Don't miss out, I love this anime, and if you like the anime as much as I do, you'll also love the manga, but that's another story...
