In my opinion One Piece is without a doubt the Greatest. Anime. Of. All. Time. No ifs or butts. The writing, voice acting, and all of the above is absolutely perfect. As of now it's up to 566 episodes and I know a lot of new comers make think "But it's so far ahead how can I catch up" it's 100% worth catching up! This series will make you happy, make you cry, make you made, and make you feel all sorts of emotions! The creator of this anime is an absolute genius and this is the most popular anime in Japan and even here in the US it's become huge and the manga is always on the new york times best seller list!
