@Markku:
I get what you're trying to say, but when you look around and see good, well-paced and well-animated anime adaptations like Gintama, Soul Eater and FMA:Brotherhood (the canon bits), Hajime no Ippo and Hunter x Hunter (and dare I say even some canon parts of Naruto and Bleach), it's hard NOT to be disappointed with the One Piece anime.
It's not just a matter of doing it scene-by-scene, what bothers me is Toei completely dismissing the opportunity to add something to what is the manga, while keeping a reasonable quality standard on high.
I know OP is a weekly anime and all (and I don't like this either, but let's save that for another day), but with all the money a huge company like Toei makes from One Piece, you'd think they'd be willing to animate, direct and pace properly one of their flagship series.
In short, I dearly love the manga, but the anime is always a disappointment. QUALITY nonstop, and this Marineford war often looks slower, smaller and less crowded than the Skypeia survival game. Damn you, Toei.
You cannot compare OP to Brotherhood or Soul Eater, they are COMPLETELY different cases. Like you said OP is a weekly anime based on a weekly Manga, brotherhood and Soul Eater had no Manga to follow weekly/monthly they already had an endgame
I wish you people will just realize that just because the Anime pads out out the Manga, doesnt mean the pacing is slow. As I have stated before, already knowing what happens in the Manga is the only reason you are questioning the pace. If you didn't know that some of the episode was filler you would be perfectly fine with it. Now I realize that some filler, like alot of the ones in Impel Down, is bad but the filler so far on Marineford has been top notch.
People need to stop deluding themselves, the Anime will never go as fast as the Manga and it shouldn't go that fast anyway. The Anime is a separate entity from the Manga and while it follows the storyline, it has to put its own spin on things.
Friends of mine that are Anime only fans have told me many times that this has been on of the best arcs in OP. Why? Because to them, and most of the people who watch the Anime, are experiencing all the greatness from that arc for the first time, instead of griping over small issues that truly don't matter. As an Anime and Manga fan I have learned to accept that they are different from each other and found that I can still enjoy both of them..
