You've got a point with KHR. I guess I just didn't expect it to go supernatural and lose its realism when boxes hit and school life was forgotten. I noticed a shift though and I liked where the story was before.
I do agree that Bleach and Naruto lost something special. I stopped reading bleach after Ichigo started invading hollow-land and saw the same "damsel in distress" idea being reused, I can't speak for that story. Still, Naruto seems to bring some (sometimes quasi-corny) life lessons out. Naruto also has a feel similar to DBZ that I like, plus the attacks are cool. What can I say. Though Naruto changed I think it was for the better. It got darker and the characters seemed to mature as I matured.
Eichiro Oda has shown some genius in One Piece though. I still think that series is 80% gold if not more.
