Name me a good ending series?
I cannot remember any from top of my head
Why is it that mangakas always shit the bed when they reach the ending?
They either rush it into a mangled illogical mess of loose ends and plot holes, or they just overlook all the character development and can't find a way to pay off the overall plot so the ending feels forced and weird.
It happened with AoT (thank god I dropped it after the basement reveal), Bleach and many others. Currently JJK is going through that.
I hope with all my heart that Oda doesnt botch One Piece ending. That would really hurt.
Same thing with Kingdom if the author decides to deviate a lot from real history and start modifying the plot too much with his headcanon.
I am currently in the Western Zhao Invasion arc (chapter 514) and I hear a lot of people dislike the Hango Campaign arc because the writing quality dropped a lot.
At least I can be certain that HxH will always remain on top since there won't be an ending
