This anime has a ton of pacing issues. I would say the pacing is far worse than One Piece. That being said just like One Piece, the world is absolutely vast and Hunter X Hunter somehow contains more of a fantasy feel. It makes you wonder what unique thing is around the next corner.
I know the manga has been on hiatus but I sure hope it picks up soon because I'd really love to see where the author takes the story from here. I wish him nothing but the best of health moving forward.
