I didn't mind the flash back that much, since it means they're doing little things to extend the episode, and in doing so, avoid fillers
As far as the quality of animation, I'm glad they seem to be having decent, consistent quality...but you guys that were comparing to Naruto, don't think Bleach has always been like this. There have been plenty of episodes where the animation has been complete trash compared to the stuff Kubo pulls in his manga. One instance that jumps to mind is Ichigo's fight with Dordonii back when they first entered Hueco Mundo. Compare the anime episode with the manga chapter of when Ichigo pulls the mask on, and try telling me that the quality is the same. I could've done a better job animating it with my left hand.
Anyways, can't wait for when Aizen decides to start fucking with everybody!
