Viability is a social construct
Hunter x Hunter's second real arc (the fight tower one) is even worse than the first, by a lot. No, nen is not interesting at all, nor is an arc about beating up cripples. Also Leorio is missing. I don't see how the show gets better if he's really this unimportant. The story really isn't maximizing its potential here. Like, imagine Leorio being, "I sure hate those guys, I want to beat them up so bad." And then Krappyka says, "Leorio, don't be pathetic, they're cripples." Slide whistle.
Also you’re in for a treat with NHK and Rakugo Shinjuu; both shows r utterly superb in their own ways. Also don’t skip the OP on either ‘cuz both fucking own.
