>>25359 I think the point is that moeshit took the "cute, kawaii!!!" aesthetic so far, that it became an almost universal style. Almost every anime today has the female characters have almost the same exact faces. Sure the 90s, 80s and 2000s had some similar aesthetics, but characters, series and OVAs still had distinct faces and designs, you could never confuse Bleach with Naruto or One Piece or Dragon Ball and vice versa. In Miyazaki's and Anno's works the characters have similar aesthetics and similar faces to an extent as part of their artistic stylization, but I wouldn't mix up Rei with Asuka or Misato or Nadia, despite similarities. Now people can edit 'moe' anime girls from different series into a single show and nobody would be able to tell the difference. It's not as problematic with male characters but still exists for them too.
TL;DR: Modern anime through the proliferation of the 'Moe' aesthetic has made many characters and anime series too samefaced.
Seriously as a random comparison. The girls in K-On, SAO, Konosuba, Love-Live and I've Been Killing Slimes for 300 Years all have similar-faced girls. Literally just swap clothes and hair colors.
