I have to agree: If this keeps going with this quality, it will easily be the best filler arc so far. I don't actually have anything to complain about so far. The animation was indeed quite nice, the story seems interesting, and even Anko's memories of Oro were pretty artistic. Naruto's near 100% failure rate with summonings continue, which is not surprising, but interestingly enough they had developed a new joke for it, so it was cool. Naruto's techniques so far haven't been overplayed (well, not that there would have been chances yet), and if this doesn't change, it would alone be redeeming. But that remains to be seen.

I'm hopeful so far.

Edit: A couple of typos.
