I love Palm. Her date with Gon while Killua has his thing going on in the background is amazing. While this arc was first being serialized, due to it's long length and hiatuses and story seemingly having nothing to do with the overall plot of HXH, there were moments when the arc seemed like it might be the worst in the series. Now that the arc is finished, it's nothing short of amazing IMO, and I can't wait to see a attempt to top it with his next big arc for this series.
Yeah, there were a lot of little moments like that where on a chapter by chapter level everything seemed… off. Especially things with Meruem and the arc's finale.
But you're right, seeing the whole arc from beginning to end (and seeing it animated now) just reinforces how everything is actually just real damn strong. I kind of love the pacing and a lot of things that underwhelmed me the first time around (again, the whole finale minus anything Netero did-- always loved that) I think are actually really smartly written out. Love it all.
