I agree! I remember when I first was getting into fanfiction, there were whole blogs that solely existed to trash talk people's Mary Sues, Mystery Science Theater style. At the time I remember thinking they were quite funny but in retrospect why did people want to make fun of young writers having fun?

I think eventually the world of the Mary Sue just gets less interesting because it is false, it is a fantasy, but... you know, sometimes I want to be the Mary Sue of my life story even now. I'm glad there's been a reevaluation of Mary Sues hehe
