Maybe if Celestia actually got some focus early on, she wouldn’t be treated as the fandom’s punching bag. But no, the showrunners were like “but we don’t know how to write for!” That’s a load of BS, there is so much they could have delved into but chose not to, only to cave into the demand of the rabid Luna fans and shove her into everything and only giving Celestia some attention when the show was nearing its end, and even then, people still feel the need to hate on her.
“But leave it to the fans to make Celestia better!” Yeah no, half of the fan depictions of Celestia are pretty awful, and pretty much assassinate her character, turning her into a troll, a tyrant, a cake fetishist, or just writing her off just to make Luna look better in their eyes. It makes being a Celestia fan difficult, but maybe it’s a good thing that her fanbase is considerably smaller. At least it’s not as mindlessly insufferable as her sister’s.
