My personal favorite for flawed reasons is Madoka because I was there for the live reactions to the infamous episode and it was magical watching everyone lose their shit. It was also my re-introduction to anime after being shamed out of it for liking sailor moon as a kid.
Utena is NOT sus, it’s about how harmful the older prince trope is and it’s also a coming of age about growing up as a queer girl. It’s my favorite anime I’ve ever watched
