That's just like your opinion man
YYH is awesome, read it for the first time last year and loved it. I never considered the story to be very important in YYH it's clearly just there as an excuse for Yusuke and co to have awesome shonen fights which the series delivers very well. Maybe if you don't like good shonen fights but then why are you reading shonen it's certainly not for the plot.
Of course it's my opinion, never said otherwise
I'm searching for a spark of story because the fights until now have been awful, they conclude themselves within 2-3 moves per character and none of those moves have some kind of strategic value, or explained, or are interesting.
It all ends up as *attack* -> "i've this ability your attacks do nothing" -> * enemy attacks* -> "urgh you hurt me but eat this attack" -> *new attack* -> "ahahah not even a scratch, now die!" -> "are you sure?" -> *enemy dies while attacking and damaging the good guy*
Now that would be good too since lots of other manga do that but those attacks aren't neither flashy or interesting to see.
It's exactly like that gif that i've posted which was a parody of shonens with the exception that the gif was a parody but this isn't.
Now if the fights disappoint what else you can enjoy in this work? Characters? Nope blank puppets as i already said.
Story? There isn't.
Art? Hardly groundbreaking.
In other shonen i can always find a redeeming factor for the problems they have but i can't find any in this so for me is mediocre.
