Hey, not bad for half an ep. First thing I noticed was, yeah the animation has improved light years from only a few episodes ago. Most of my opinion on the spit/sweat thing has been said, but if it continues it will be disappointing. The fight was ok, ok only because, well, it was short, and didn't do much. But hey, a fight is a fight, right?
(Aside: Does anyone else kind of want Ichigo to let the hollow side of him loose, and then go on a bad-ass murdering rampage one time? I think that might make for a decent filler arc, but whatev.) Hells yes for Benihime and Uruhara though, that has to be one of my new fav. zanpakutos. I think also I heard some new music? It's about time
Afterwards though, except for the rest of the team showing up, more than half this episode was time wasting filler. Even using the excuse to keep from having to do another filler arc in a few months, it is incredibly unpleasant to have half an ep. be really good, and then shoot to Yoruichi eating everything she can get her hands on.
