One Piece
1999 · 21 Seasons · Fuji TV · Adventure / Fantasy / Action
One Piece is an anime built on ambition, and across more than 1,100 episodes it delivers on that ambition more often than it doesn't. The world Eiichiro Oda created is among the richest in fiction, and the bonds between the Straw Hat crew carry a kind of emotional weight that few animated series have matched. Pacing problems and inconsistent production quality hold back the anime adaptation from matching the heights of its source material, and the sheer episode count will scare off anyone who isn't ready for a serious commitment. For those willing to take the voyage, though, there's a reason One Piece has captivated audiences for over two decades and shows no signs of slowing down.
