I watched a few InuYasha on TV, and looked at a couple online. Then I went to other things.
My problem is that the series seems to be made more for a US audience than, say, a Japanese audience. It is too loaded with violence (violence is the big turn-on for US audiences!) and not enough work is done developing a coherent story. After a while it looked like the people doing the writing were just writing something -- anything -- to keep the story going while it meandered toward nowhere.
It has been a long while since I watched InuYasha. I haven't missed it.
