I really dislike fillers. Actually, dislike is an understatement. Having said that, this was actually a pretty good episode.
The coreography was ok, animation was good and art was decent as well. Sound was spot on and it made it really interesting to watch. What really made me like it, however, was the fact that this fight, the way they fought, was actually what I thought was missing in their final fight in the manga.
It started with OP attacks and then they just skipped to drained base forms and duked it out like that. There was nothing wrong with that, it was interesting to see, however I always thought that it lacked the standard, basic action sequences like rasengan-chidori (I don't mean the final one) and actual non-wasted taijutsu.
This fight gave us a glimpse of how it could have looked and for that I'm really grateful.
