....Sorry but regardless of the vocal minorities of the Cadance dislike, I still like this character.
Luna is easily more relatable to most people, Celestia is harder to understand but easy to like her personality from many people, and Cadance herself.....
Dunno but probably since The Canterlot Wedding was so well received, she and Shining Armor were already beloved by almost everyone for their personality, designs, voice acting, or appearances (as in what's shown and seen).
Me, I already disapproved the idea of Cadance being evil even before the finale aired and what annoyed me was that there was already people disliking the character (and probably Shining Armor to an extent) thanks to the fanon's rules of "OC alicorns (Winged Pegasuses) or additional alicorn princesses are never allowed" and plentiful of those degrading memes thrown at Cadance almost all at once.
Thankfully the finale won the fans Cadance needed for the most part and I'm rather happy for that.
