That's too bad, but I can see how it happens. One thing is to distinguish between the animes and the mangas. The animes tend to really suck (this applies to Bleach and Naruto for sure, probably One Piece too). The mangas are usually better.
If you're new to One Piece, it might feel weird to come in at chapter 500+ and get used to the art, but it's worth it. Especially if you have time to go back to the start of the series and catch up on the backstory. That's what I did, when it was back at chapter 400 or so.
One piece the anime ROCKS. Even the fillers rocks.
