I have to say that was the lamest fight ever in Bleach... not counting filler material. I realized that Rukia would somehow end up winning when the whole flashback sequence started but I was hoping it would be a bit more impressive than that. Seriously, it made no sense whatsoever that Aaroniero Arruruerie didn't push her away when she started her technique. Instead, he just sat there in stunned awe and waited for her to finish him. I have to wonder how the hell this idiot managed to defeat 30.000 hollows let alone become an Espada.
What pisses me off the most is that Aaroniero Arruruerie was a really interesting character with a wide assortment of skills. He could have made for a very interesting enemy with his ability to use the skills of the hollows he had consumed but instead they opted to kill him off in this idiotic fashion after having hyped him up for several episodes. I'm really disappointed with how this character was treated and in general I feel disappointed with the Espada.
Bitching aside, I did like the music present in this episode. It made for some awesome build-up. Too bad it had to lead up to such an anticlimactic ending.
