Recently Yoshihiro Togashi, mangaka of Hunter x Hunter and YuYu Hakusho, gave an interview where he talked about HxH's ending.BERSERK should have died as an unfinished masterpiece.
If they wanted to release a cliffnotes version to give fans some kind of closure, that's one thing. However, it was always 'optimistic' to think that a seminal work that was so masterfully auteured could ever be continued in the same format without its author.
He gave them a short ending "in case he passes away before he manages to end it himself", imo pretty much stating he doesn't want the manga to continue after his passing.
And even though he said that, I somehow still think Shueisha will find a way to continue his work if that ends up happening...
We really need to start letting these unfinished masterpieces stay as they are instead of sullying their names.
Especially in huge works like One Piece, Hunter x Hunter, Kingdom, Dragon Ball, Detective Conan etc, I don't doubt their publishers have already thought of who they'll hand over the manga to in case the author passes away. Obviously I have no way of proving that, but I have a feeling.
