Well, after watching it a bit the thing that bugs me is the amount of content left out from the manga. All in all though, pushing the manga aside, it is a alright show but can't really get into finishing the first part.
I didn't. I can tell you now that most of it is filler. I started skipping around before episode 100. I watched the Band of Seven episodes but I started skipping around again though.
That was one of the things that kept me from watching Inu Yasha. It seemed like some soap opera where you'd basically be lost if you didn't watch it from the beginning. That and the amount of rabid fan support that materialized around it. Since they started replaying it on Adult Swim I find it's not exactly as bad as I thought it was. Worth a watch at least.
Most of the early 100's are fillers. Episodes before 100 are fillers, but Final Act seemed so much better than the original series, but that's just my opinion.
I don't really mind that there are so many eps. If there was not sooo much filler and more of the core content from the manga (manga had a few filler moments also) I would enjoy it more to the point to watch it all.
