With the Soul Society Arc finnished with and the actual story of Bleach not far in front, the producers of the Anime needed to give Kubo Tite time to get more chapters of the Manga out before continuing the story, thus the beginning of the 'Filler' Arcs, with this being named as the Bount Arc.
The story revolves around two of the main cast more than anything else, Ichigo and Ishida, with the story focusing of Ishida's attempts to hide the loss of his powers in his battle with Captain Kurotsuchi.
The story revolves around the beings called Bounts,-humans who eat the livings souls-and their attempt to wreak havoc in Soul Society, in comparison to the overall story, it does fall short with less time on some of the human character, but if you are either an Ichigo fan(and who isn't?) or an Ishida fan(again, who isn't?) than this season of Bleach is the one for you.
There's plenty of fighting to be seen, far more use of Ichigo's Bankai and more of a look into Ichigo's Mask.
