Yeah I don't get what this is trying to say, naruto and bleach are just two really popular series during the 00's and early 10's that I feel like when I ever se it brought up its just people generally complaining they go downhill in quality especially near the final arcs. Bleach more than the other, I see a fair amount of people that still liked naruto all the way through, bleach seemed to anger just about everyone by the end save for fans of the winning side of the love triangle that never actually was a love triangle in the first place.
(going bit off topic here) God even talking about naruto and bleach makes me feel old, the landscape of jump has changed so drastically since them and all traces of jump from the 00's they were prominent in have all ended after gintama finally called it quits last year. Outside of one piece (which is in its 2nd to last arc) and the zombie of hunter x hunter that shows its face for a few weeks every year or 2, theres no manga running anymore that didnt start in this decade and closer the middle of it at that. And hell even there alot of them are close to ending too as is with 2 of the biggest names right now, yaiba and neverland, both in their final arcs. Then you go and look at how the naruto guy's new series is pretty much on the verge of cancelation, its pretty alright if you like the style so its a shame to see it get cut short, but recent chapters already feel like they are setting up the rushed end, its called samurai 8 if anyone wants to read a potentially doa series.
