One thing I love about HxH when compared to other shounen is that the slower episodes like this one are still pretty interesting to watch because of the smarter dialogue in them and the strategizing even though there isn't much action, and because they'll always serve a purpose. Some people think this arc is too slow but honestly none of the episodes from this arc are as slow as the appraisal one from Yorknew or some of the Hunter Exam's slower episodes.
