1 – it wasn't because of Twilicorn per se, it was because the whole episode felt rushed and was very badly written. Forgive the spoilers, but THIS FIC shows how to do Twilicorn right: fucking dark and fucking epic.

2 – Equestria Girls was bad because it had a totally unimaginative setting. It could be set in ANY era and ANY location in human history, and what do they do? Contemporary Murican high school. FFFFFUUU-

3 – People dislike Flash because they dislike EG because of item 2 above.

Well, my slightly snarky response would be, "being in a position of authority means you'll have to learn to deal with people who don't like you or your actions."

I've never been a fan of sympathy-bait posts like this.
