For anyone who reads the One Piece manga, and is up-to-date, this is the thread for you. Otherwise, beware of spoilers and so forth.
One Piece has been getting really good lately, with the re-introduction of Buggy as a serious character, and Bon-chan back to support Luffy. I also like the somewhat darker note it has taken since Luffy arrived at Impel Down. What with having his skin melting from acid and poison, Ace's soon-to-come execution, and even the darker sentiments expressed by Bon-chan's okama idol, who's name is beyond me at the moment.
I'm really dieing to find out what's up with the rest of the crew, though. I imagine their stories won't be as long as Luffy's, which I wouldn't really want as it would take too much time and focus away from the goal here, but it'd be interesting to see what is going on with them at some point. Oda will probably finish Impel down and have Luffy track them down.
But first, I want to know what's going to happen to Ace. We know Oda hasn't been pulling punches lately, so I think it's safe to say his fate is fairly up in the air, at least in the minds of the readers.
