It's been about two years now since I've seen a Naruto episode and judging by the comments here it was a good decision to have stopped watching. The only way I'd watch Shippuuden is if they took a page from Dragonball Kai and re-compilate all the episodes removing ALL fillers. And even then I'd still debate watching the anime.
“Pirates are evil? The Marines are righteous? These terms have always changed throughout the course of history! Kids who have never seen peace and kids who have never seen war have different values! Those who stand at the top determine what's wrong and what's right! This very place is neutral ground! Justice will prevail, you say? But of course it will! Whoever wins this war becomes justice!”
