This is one of my favorite chapters. The art is pretty bad, yes, but look at the STORY. It's brilliant. I re-read it right after finishing it. The Koala man (forgot the name, if he had one) is a very interesting character. Good depth.
And I think the lenght of Kaito's and Gon's reunion was enough.
We can always hope the art will get better soon, and if not, we'll just have to deal with it. It's better than nothing.
