Mary-Sues and self-inserts in fanfic have been a thing forever, this whole crop of "I need characters that look like ME otherwise I can't enjoy this" strikes me as something a bit different than just reading too much fanfic, I think narcissism (They're the center of the universe in their eyes, of course every show should cater to them) more than anything.
