I personally have no worries about the anime catching up to the manga. We have looong ways to go before that happens. But I can't help worring about censoring and about the Yorkshin arc. I pray censoring won't kill important moments and the Yorkshin arc will look no less incredible (prefereably more incredible) than it was in the 1999 version, because that we won't get another remake, so this one has to be perfect or almost perfect.
To be frank i don't think the 2011 anime has that much censorship compared to 1999. I think it'll be handled well enough.
If little kids were watching this shit they would be bored as hell. There hasn't been any major fights so far.
I can't help but worry they are going to rush through this arc. I don't know, it seems like it would be logical to say that it it will go 9 episode, but part of me feel like it will be much shorter. So nervous. :P
I highly! doubt madhouse is going to rush through heavens arena. If anything they'll add more to it lol.
Some of my favorite scenes happen in this arc. I really like how Killua's character is handled especially. Basically everything he does during this arc shows how much of a badass assassin kid he really is. His intelligence, instincts, and overall personality really shines in this arc which is something i really want to see.
