https://www.animefeminist.com/discourse-not-doll-rei-ayanami-escapism-objectified-images-desire/Here's some recent feminist article about Rei. I didn't read all of it, seems like its main purpose is to tell that you shouldn't like Rei bacuse of her beautiful looks. They call it "fetishisation".
Seems like typical nonsense about objectification and narrative about why guys shouldn't care about girl's looks.
