Bleach was the first manga i've become addicted to.
The Storyline was just great, the art and dialouges were hilarious and it had that little something that made you read a chapter twice, even three times and change your mind about it completely. The author never disappointed me to a fun read and an all around good shounen manga experience.
I've even gone so far as to defend this manga in different forums from (IMO) unfair criticism, like it being too slow paced or being ridiculed by it's own author by powering up the main character.
( I mean, seriously, its shounen f.c.o.l., the hero MUST win against the main baddies no matter what!)
I loved its getup and even the little inconsistencies in the storyline, for which it was bashed so often. I was even a little fanboyish, ashamed as i am 'bout it XD
But recently, i've been looking through the manga I posses and read online. While I reviewed the bleach chapters since the end of the arrancar arc as a whole, i felt like being splashed by ice cold water.
The first I noticed the somewhat diminished form of the drawings. Everything feels rougher and not drawn with much enthusiasm, as if the author, for some reasons, was not completely satisfied with the way things went.
The story, which i've found all over entertaining so far, changed drastically and to a point where it was completely nonsentical and even I failed see a point in developing in that way. The whole "getting back the POWER" - arc felt like wasted time, for it's conclusion being: We'll give it to you anyway, because WE want you tou be with US. Ichigos own struggle was as good as pointless, which isn't a good thing at all for the main character.
In the recent quincy invasion it became even worse. It seems that Kubo is only interested in showing of all the site characters powers (read Bankai!) not been seen till now, the quiet inventive, yet totally unbalanced powers the quincys posses, and, above that, some really disturbing and trashy background stories of enemies that were introduced, roughly, 50 penels before.
(While writing this, the freakishly strong kenpachi fights a quincy who can create reality out of his imaginations. Perhaps I'm mistaken, but isn't that like fighting um... God?)
I my opinion, Bleach should have ended with Aizen's defeat and Ichigos goodbyes.
There would have been a few loose threads and stories not told, but nonetheless a good and satisfying ending.
Now Kubo put his complete wor through the ringer and developed a story getup that will serve for, at least, another two years. I am not convinced that i will stick to it till the very end.
If you hadn't read bleach so far take my heed and don't continue after ichigos great win. it will depress you and it's almost not worth the trouble, sad but true.
