To Kubo Tite:
"Bleach" was a good manga once. The characters and the premise were strong and interesting even if the setting was shaky in some ways. Your fans hoped everything would grow and be improved upon and for a while that was indeed the case.
Now, 11 years later, "Bleach" is a parody of itself. The characters have been static for years, and apparently even some of their power levels haven't changed, except for Ichigo's--always except for Ichigo's. For example, the entire "Xcution" story arc was merely a vehicle for Ichigo to regain his powers, but was otherwise entirely pointless, from the boring new characters and their totally vague motivations on down to their bullshit Fullbring powers, which I'm sure we'll never hear about again. The whole thing read like an anime filler arc. Granted, Ichigo is the protagonist, but even he's static as hell, and you peopled the manga with many characters who had the potential to make contributions and draw readers in, yet you never gave them the chance to do that. The only changes are their hair and clothes, which is pathetic, to say the least. Sasakibe is a case in point of your repeated failure to take the opportunity to develop your own creations. Your readers knew next to nothing about him and then you killed him.
Speaking of killing characters, it's downright unkind to keep your readers in suspense over the fate of characters like Byakuya and Kira, who may or may not be dead, as you insist on reiterating one way or another in nearly every recent chapter. Take a hint from all the death threats on Twitter and let us know one way or the other. Waffling is universally despised. And if you're trying to maintain if not gain new readership in light of falling sales, it's backfiring in a big way. Also, pandering to your remaining fans by bringing Kenpachi in to bust heads only represents another failure on your part. All it means is that your material is garbage and that you know it's garbage, so you're grasping at straws. It smacks of desperation.
Furthermore, please stop showing Ichigo struggling frantically to escape the cage in Hueco Mundo. Multiple panels of him screaming and thrashing about are not needed in every chapter. If he's not managing to escape by himself or being released by someone else, stop showing it. Your readers know his situation and do not need it repeated every week; you're beating a dead horse at this point. You could use those pages more productively and move the action along elsewhere. You are wasting opportunities at every turn and it's just sad.
It seems that you don't know what you're doing as a mangaka. Your story meanders like a delirious man lost in the desert, your characters are frozen in developmental glaciers, and you're pulling events out of your ass, and guess what: THE SHIT SHOWS. I don't think you had any plan going into this, and you have not fleshed out the world that you yourself created. You try to cover your ten-mile-wide plot holes with waves of new characters and big action panels, but those tactics are as transparent as air.
All that said, I actually don't put all the blame on you. Your editors and assistants should take some flak, too, for not catching the innumerable storytelling flaws and pointing them out and bolstering your drafts where needed. There is a whole group of people responsible for "Bleach" and they have all let it get to this point.
I suppose it's in my nature to retain a smidgen of optimism that maybe you'll redeem yourself. Maybe the plot will take a turn for the good and I will be pleasantly surprised. I want to hope for the best, but I am expecting the worst. You've let me down, and I'm not the only one.
From a disappointed fan
