From what I can gather in this board, it seems that more and more people seem to lack interest and are disappointed with the current CP9 arc.
Interest? Or just not as vocal? Honestly, what is there to discuss? Everything that Oda has been building up to for the last two years has come to a head and we're now moving towards resolution. Something of this nature hasn't happened since mid/late 2003 when Skypiea started winding down.
Two people are fighting. The fights are interesting. What more is there to say? As far as guessing where this could head, I easily see this as one of the most perplexing resolutions so it isn't even worth discussing. I think many posters here will agree that even spending more than a few minutes discussing possible outcomes is worthless since there's just SO much that could transpire.
Now compare this to two years back:
Robin left with a masked person who just said "CP9"
A new villain, Franky, had just been introduced
FREAKING USOPP LEFT THE CREW AND FOUGHT LUFFY HOLY SHIT
Merry was delcared dead
A new island with countless possibilities
Now we've got fights. Two people fight one another. One wins. The end.
Maybe you could discuss in detail whom might fight who but now that's been almost totally cleared away so little else is left to the imagination.
I totally agree that activity has been down, but that's because there's little to discuss at length at this junction and most of what is up for discussion has already been covered.
They say that fights are boring and too rushed, and they are starting to think low about One Piece.
Okay but does that mean every OP fan thought every battle in OP was perfect to this point? There are a bunch of battles I felt were totally worthless in the past. We don't need to shower Oda with praise if he doesn't write something that tickles our personal interest. I do believe that as a whole in this arc we can all find battles we liked and disliked. Saying we dislike some doesn't mean the whole story is hopeless.
