Books like Berserk, volumen 40

I don't recall reading another fictional series that has changed so much like "Berserk". It started in the eighties as a savage, brooding, dark as hell (quite literally) story that for many defined how gruesome this genre could be. These days the series deals with most of the characters we are familiar with (those that have survived), but they involved with hijinks that fall into the high fantasy genre. This is now a story about adventurers sailing to the land of elves so the "king" of that land can help them navigate through the dreams of a cursed person to recover her memories. It used to be about literally battling demons to save your loved ones from being raped and devoured, or meeting a nice family only for them to get raped, dismembered and mounted on spikes by a monstruous pursuing army, or rescuing naked female villagers from a nasty cave in which far nastier trolls rape them repeatedly so the women will give birth explosively to a new brood of trolls. These days the author draws some gruesome foes almost because he should, instead of because the mood of the story demands it. In the middle of it all, our protagonist Guts, a big, brooding swordsman who when he gets into his berserker state he can't tell friend from foe, is now like an anachronism: the lost and obsolete survivor of a bygone era.The author clearly loves his characters. He's been with them for decades, and at this point they are almost his children. Unfortunately you can no longer believe that the threats they face are really serious. Guts' posse includes a child and two teenagers who never get harmed in any significant way although the group faces nasty opponents. "Berserk" at this point is not so much a dramatic series but a way to hang out with characters you are fond of. I'm not mad about it: I'll keep reading. But it's quite clear for me that the series will end with the author's death. Are we really to believe that Guts is in any position to (view spoiler)[stop Griffith? And why, despite Griffith's "number one anime betrayal" in the turning point of this series? If Guts somehow manages to destroy Griffith, there goes the last hope for humanity to survive in a world that has turned upside down. And it doesn't seem that our protagonist wants to bother (hide spoiler)]
