Bleach was a good anime and a good manga for a little bit. Seriously, it had its own distinctive style despite telling a story that is very familiar to a shonen veteran (i.e., for a while it was Yu Yu Hakusho with better fashion sense). There was just something I enjoyed about the series when it was still ghost hunting in Karakura that just disappeared as soon as they entered the Soul Society. Don't get me wrong, I actually liked the Soul Society arc; it introduced a lot of very interesting characters and ideas. But it just wasn't the same show anymore. They went to this new location and introduced all these new characters and never really left. What I had hoped was a fun-filled vacation was a full-scale relocation. And everything changed about it; the characters (which ones are focused on, particularly), the scale, the scope of the stories... It just wasn't the same. I loved Bleach for the first 20 or so episodes and the first 7 volumes, but it up and changed from a familiar story with a refreshingly new style to a familiar story that I didn't like that much the first time.
I liked Bleach when it was Yu Yu Hakusho. Then it turned into Dragonball Z.
