I actually really liked how the Gon and Killua splitting up was handled. It was definitely emotional, particularly with how they didn't want to part and the way they looked when they turned away from one another, but it wasn't overboard. It was well done, imo. And, this scene between Ging and Gon was much better than the first one. Really interested in this "other world". I guess this would explain why Ging is so hard to find, haha.
