Cadance is a boring useless dumb pretty bitch. She got way too much screentime.
No, the problem is that she’s getting too less screen time and yet the show goes above and beyond the call of duty to make her out to be this major character (almost to the point where the show thinks it’s all about her) when really she’s just a glorified background pony whose majority of screen time was actually someone else disguised as her.
She has potential to grow, especially with Games Ponies Play making her out to be a pseudo-Celestia (watch the scene where she’s about to scold the girls when they explain they got the wrong pony, I got heavy “authority figure” vibes from her), but the problem is that she needs to grow while sharing the screen time with the Mane Six instead of absorbing them and going “HERE I COME TO SAVE DAH DAAAAAAAAAAAY!”
I also dislike how Twilight never fails…I mean, she’s not perfect.
There were some times where she failed. Yes, she managed to fix the problems and at one point was actually right about something, but she has failed at some points.
Failsafe Spell, anyone?
