Here we go again... The only reason you should watch fillers is if you need to kill about 22 minutes of time. That, or if you're a manga reader, to see how badly they can fuck up a good thing. I'm not sure about this, but apparently (from what others say) they've fucked Bleach over pretty good.
I'm starting to miss recaps. Someone, please shoot me.
