The more I think on it the more I think that chainsaw man is like a modern day evangelion. And the people who are hating on the ending of CSM are the same people who would hate the original tv ending of Eva. What I mean is, that when Eva originally aired, a lot of people cared more about the giant fighting robots, the Christian symbolism and phrases used, and the concept of SEED as an organization, but none of those things were ever what Eva was about. Eva was always a character study of this depressed boy and what it means to find happiness. And chainsaw man seems to be doing the same thing. It sets up nostradomus, the 4 horsemen, the background noise of what is happening in America and the Soviet union and how the Japanese elite are using deals with devils to progress their own agendas. And again, none of that mattered. Chainsawman, like Eva, was always meant to be a character study of this sad depressed boy and what it takes to be happy and follow your dreams. People for both Eva & CSM were upset by the lack of plot resolutions at the ending but the stories were never about those plots, they were about the thematic questions they were pondering and both times the last two episodes/chapters stripped the stories down to their bare essentials and left the people who cared more about the fluff out to dry. And im not saying this to imply the people who enjoyed the fluff are wrong for liking those aspects of the stories. but moreso to comment on my observations that most of the people who disliked the ending of these two pieces of art were moreso wanting different things from the ending than what the author was every trying to convey.
