Negima! needs a proper anime, really there's no question.
Baccano!…seriously, guys? The anime was great, and while not exactly the most faithful adaption of the novels, it was a solid anime and got everyone interested. Narita is really milking the novels and doing things like killing off popular characters and bringing un-popular ones back to life. Would you guys really want to see that kind of stuff animated?? I mean the desire for a good show to continue being good is really strong, but if it's finished and done well, it's done. Rarely do you see a story maintain quality over long iterations.
@firecrouch:
Contempt? No I wouldn't go that far, it's their cash cow. But yeah they know people will watch it as long as it goes on so dragging it out is no problem for them.
One Piece isn't even Toei's biggest franchise, PreCure is, and PreCure gets premium treatment in comparison.
OP's anime has been horrible for a long time. I wasn't a huge fan of it during the early days, but it was still good up through Arabasta. Uda just couldn't adapt to Oda's own change in pacing and the result is an ugly, dramatically inconsistent mess.
