I had hopes for Shippuuden in the beginning, but it will continue to suck as its director is a complete idiot. It is and will continue to be plagued by excessive amounts of filler. The Pain arc could have much more awesome if the director hadn't taken away all the best animation directors to film the movie, which turned out to be crap from everyone's comments. You're much better off reading the manga and watching the parts that interest you. The Kakuzu/Hidan arc was animated pretty well, though.
