They weren't fillers. They were just recaps from where they last left the arc for the fillers.Even though half the episodes were fillers it was still good. I mean the 5th espada was pretty cool the C looking sword dude but it was kinda harsh what he did to grimm jaw though, but I think that grimmjaw is going to get healed by orohime and help out ichigo on his conquest to kill aizen, but over all good episode it was very good.
