When she's not fronting, I actually rather enjoyed trixie. I can definitely understand the hate, as i originally did hate her too. I went back and rewatched the episode actively looking for what was making everyone else fanatical about her, and shockingly actually found something. If you look at her more as a desperately broken ego traveling and putting on shows in small towns to scrape a living, then her ego becomes less of a huge annoyance and more of a sad attempt to make herself feel better that should be pitied rather than hated. I just kinda feel bad for her now.

I hope she shows back up in some sort of redemption fashion. Maybe finally tired of having been run out of towns or being disliked, haunted by the shame of "The Ponyville Event" she comes back with a lot more humility? Until Cranky showed up, I'd say she served as the only pony in equestria not living an idyllic life. That, at the very least, makes her a unique character if not a likeable one.
