I haven't seen a lot, but from what I've seen, the One Piece anime is the greatest affront to a creation one could possibly make. I've heard people badmouth One Piece (the manga) 'til they were blue in the face, and I wasn't as absolutely shocked, appalled, and downright disgusted as I was when I saw One Piece. Jeez, I'm getting pissed just thinking about it. Good riddance.
