In this part of the series, how cán the filler enemies be anything but pussies? Since Ichigo etc. should be kinda on par with Espada, it's weird to introduce an enemy that is as strong as an espada.

This filler arc didn't annoy me or anything, it was well done IMO. I prefer story progression, so I don't mind them wrapping this up. I don't know hów close it currently is to the manga, so I don't know if this is a good thing or a bad thing.
They can always make a filler with some other captains that fight arrancar or something on earth. As long as it isn't another cooking ep, I'm fine with it.
