Well, I don't buy a whole lot of anime series. So no, probably not.
I own all of Fullmetal Alchemist, Cowboy Bebop, Ghost in the Shell S.A.C, Gurren Lagann, and Death Note.
And I'm buying Naruto and One Piece as they are released, avoiding paying for filler episodes whenever possible(I still absolutely love the fact that Naruto cordoned off the filler hell on separate volumes, so I was able to skip maybe 7-8 whole volumes of Naruto).
These are all series I consider "excellent" and all of them are higher quality than One Piece fillers.
My sentiments exactly.
