Inuyasha would have been good if it was 1/3 of it's length IMO. "Character Development" rarely happened, and when it did, the characters went back to their old selves anyway. After an episode that seemed to bring Kagome and Inuyasha closer, they were back to their old ways. Same thing with Miroku and Sango. Basically any time you thought you saw some sort of development, it was completely ignored in future episodes.
I dunno, I don't like it.
