Don't get me wrong, I don't hate Bleach. I do love some of the Espada (Grimmjow, Ulquiorra, etc.)
Hueco Mundo's dragged on a bit too much for me right now. Luckily the manga's at a part which everyone's been waiting for in this arc.
Also, 'Turn Back the Pendulum' was something I really enjoyed, especially since I think Hirako's awesome.
If Kubo didn't drag on the fights for the lesser important battles, it would've been fine. At least we got to see the Captains fight again though.
Maybe Hueco Mundo gave me too much deja vu since some of it seemed to similar to Soul Society.
