First off this episode itself wasn't all that bad I like the rogue shinigami and his overall story and hey if your going to put in filler the concept isn't that bad.

The problem I'm having with this is that Rukia of all people is 1 hitting Menos Grande when the heck did she get anywhere near that powerful. The result of making Menos look like such udder cannon fodder hurts the overall story for me.

Its one thing for Ichigo to do it its another for someone well below even a vice captain ranking wise to be doing things like that without releasing or using any sort of strategy or heck even breaking a sweat.
