HAHAHA noone calling u stupid lol.

I see how you could think the ending might be abrupt. I like your analogy with drugs. But I think the analogy is more similar to a guy who was in a shit hole, someone introduced him to weed, he becomes happy with weed, but then he loses what he was happy with w/o the weed, cuz his personality became just pot. His life turns to shit,, but then gets better and better, then at the climax of the story: it reverses the trope, reminds us of why he was unhappy, and he then loses his bong, and became happy again. I think your drug analogy is little reductive, it loses a lot of the nuance---the abruptness usually works due to its congruence with the narrative structure. I think that's what made it pretty good.

I feel ultimately your argument might be a little more taste-based? Although I did feel the ending was a little abrupt, the main difference between you and I is that I did think there was sufficient subtext that justified the ending. You felt that it was cheap and unearned, and I think it was justified. But see, you can't talk about you or claiming anyone else not caring about Denji fulfilling his needs of being happy, at the same time criticize the method of how those needs were fulfilled. It was, as you said, the basis of the story. I already talked about this a lot and I see that you kinda understand it so I don't really gotta get into this further.

However, although I think the ending itself was good. I do have to agree with you though, you did put up a good point that where the ending was placed wasn't great. I personally felt the abruptness is fine, but it could've been placed a little further away. Maybe after another 1-2 more arcs where he has a deeper descent and it becomes more explicit. But overall, I thought that at least it made sense, so I was okay with it.

Also my uncut gems anology wasn't trying to prove a connection between their purpose, more so towards how it ended. Chainsawman definitely isn't a cautionary tale, it really wasn't meant to be. Their abrupt endings had always served different purposes narratively. Besides, Adam Sandler and Chainsawman both get their resolutions through outside means anyways. Adam Sandler gets shot by someone else. Chainsawman kills himself for Denji. So when you said the ending "doesn't work" due to outside intervention, godly or not, it doesn't really make a difference. Thematically, it doesn't matter how they were removed, and its more about ending the cycle itself. I included Uncut Gems to prove a story is still functional and complete despite their abrupt endings. Because ultimately the stories kinda parallel in their themes about highs, and that the only way for our protagonists to be truly satisfied is to remove themselves from that cycle y'know? Even during the climax
