I look forward to the future and hope for an arc in HxH's future like this. What this arc excels at IMO are two things: a) HUGE tension of a far greater force than the protagonists b) seeing the growth and evolution of the main 4 protagonists as well as the strength of their TEAMWORK, which is just beautiful and epic. There's also their deep friendship, which you REALLY see, and I just love how much they're willing to sacrifice for each other. In addition, the Spiders are such an amazing enemy organization - so few enemy organizations are shown to have such deep friendships.

Its actually really rare and touching how much they care for and lament Uvogin's death. It humanizes them so well and makes them so much more complex.

Lastly, its interesting to see so many side things going on that tie in, such as Gon VS Shizuku in arm wrestling and Hisoka's ulterior motives.
