The entirety of Greed Island isn't bad or anything but it's definitely the weakest Arc in the anime. It doesn't feel video game-y enough, the whole system with cards can get confusing, and the new characters (besides Biscuit) aren't really that engaging. That being said I love this show so it's still an enjoyable arc with some really great moments, and this episode is the best in the arc. The fight scene between Genthru and Gon is honestly pretty thrilling despite how boring The Bombers are, and the payoff is rewarding and just nice to see. At this point in the show it's just so great to see how much growth Gon has gone through, and this episode encapsulates that perfectly.
