@FawnOverFun I know this was framed comedically but I drank half a liter of coffee this morning so like, might as well say a couple of things, first off of the properties mentioned here Bocchi doesn't have a sad ending and arguably Fear and Hunger doesn't either if you take the creation of logic in Termina to be a good thing.
Second off I'm entirely capable of liking and finding meaning in art with sad endings, Don't Look Up is one of my favorite movies.
Third off even if I didn't like sad endings they don't make me depressed, at most I don't think they emotionally resonate with me.
Fourth even if I did dislike it on that level I didn't make any prescriptive statements about how they should be, only described my feelings about that kind of theme.
And fifth, yeah dawg I know some media makes you sad, there are different ways to be sad though and I find some more meaningful than others, my favorite book I read last year was about three drug addicted middle aged men dying in a nuclear explosion and I loved it because the ways in which the narrative balanced its plot's tragedy with moments of respite and resistance was really beautiful to me.
