So my impressions so far:
Greed Island Arc:
Not a fan of this arc. It felt like a step back from the excellent Yorknew City arc. The arc's antagonist is so forgettable the only thing I can actually remember of him is his alias. Hell, that particular part of the arc was rather dull compare to Gon meeting Razor and trying to get a win out of him. At least Razor was connected to Ging, somewhat advancing the story. The bomber was just that. Forgettable. Overall, the whole arc felt like a long ass training montage. Yes, I know that Ging designed Greed Island to be a training ground for Gon.
Chimera Ant Arc (so far):
Kite, man. Such a badass. I cried when they showed that shot. You know the one. There were some things I didn't like and those involved some events taking placed after Gon and Killua escaped the forest and before the palace assault. That whole Palm date thing I felt was unnecessary. And then there's the whole sending a small group to deal with an army of Nen using Chimera Ants. And waiting a whole month before dealing with the threat? I mean I know they have to scout and all but man they took their time doing so and because of that, the Queen Ant was able to give birth to Meruem.
Edit: one more thing. Bisky needs to show up more often. The interactions between her and the boys, specifically Killua, are hilarious.
