The worst thing about a long series of fillers is that it messes up the consistency of the series. Both Naruto and Bleach's animation consistency got messed up during and after the fillers. Bleach does look a lot more consistent than Naruto though. Shippuden has some great looking episodes, even non-fight ones like ep 35, but at the same time pretty bad ones. I just wish it were as consistent as the previous series, before the filler saga of course.
Seeing as the manga has just recently reached chapter 400, how about some discussion?
I'm really liking how the plot is turning out. I was scared Itachi would be revealed as some "goody-two-shoes" (couldn't think of a better expression) after Madara said that all he was doing was protecting his younger brother. He turns out to be a good person, though someone capable of killing off his whole clan to ensure peace. I wonder what Sasuke's going to do now? Also, I'm hoping the focus returns to Naruto soon and that something will happen in the plot that gives Naruto's friends a chance to shine.
By the way, here's what I consider the best fighting track in Shipuuden. It's from the movie's soundtrack and I really hope it'll be used in the series:
