@Greg:
The animation stopped improving after the end of Arabasta. Every once in a blue moon there's an episode with decent direction or style but the overwhelming majority of it is garbage.
Fans should be outraged that Toei is probably making the show for pittance and raking in a fucking fortune. This has bothered me for 4 years now but, as opposed to the opening, there's literally nothing that can be done about it.
I disagree with this 100%. While some may say the anime is nowhere near as good as manga, and therefore, sucks. I love the anime, I look forward to watching every episode, and aside from some filler have never thought that there was a truly terrible looking episode, or one that was badly directed to the point of me hating it. Bleach on the other hand, has some TRULY terrible looking episodes, to the point that the way the characters look is off-putting (Ichigo having a tiny arm, colors messed up, etc). People complaining about One Piece as an anime need to realize that compared to 90% of anime that comes out (sorry, I might be biased because everything is harem, sci-fi, or vampire garbage, and the days of stuff like Bebop and Trigun are over) One Piece is a masterpiece, at least in my opinion.
As for the opening, I hope it's out today, being able to hear it before it gets released would be pretty awesome.
