Lucky Star and K-on for CGDCT
Evangelion for meta-commentary and deconstruction, to the point that future works that qualify often get called the “Evangelion of <genre>”
Fullmetal Alchemist Brotherhood and Attack on Titan for battle shounen
Bocchi the Rock for girls band anime, specifically
Lupin III: The Castle of Cagliostro for pretty much all of Ghibli
Akira for 90s anime


The closest that would fill Bocchi’s position here IMO is BanG! Dream. However, five years passed between the first season of Bandori and Bocchi. Only a year passed between Bocchi and MyGO!!!!!, Girls Band Cry, Jellyfish Can’t Swim and the Night, and more girls band anime released after those three.
I don’t think that means Bocchi is a blueprint for anything.
