Personally I have a love-hate relationship with this episode.
In my opinion, (No offense to Larson) the episode was not really well-written. I love Starlight and all but I think Spike should've taken her spot on this one. The CMCs haven't learned much of the "popularity" thing yet. Fluttershy's scenes irritated me for some reason; I don't like the new Fluttershy. While I like the fact that she's become more assertive, she's been using that on the wrong types of situations (like in the latest episode, "A Health of Information," she used her assertiveness by pushing Twilight and the safekeeper of the house away when she needed to rest) I also think the episode needed to cover more stuff than just the mane six, like Derpy worshippers and clashings of Princess Celestia over the so-called "Lunar Republic." Rarity's anguish broke me I dislike those Rarity haters for saying she was too much of a socialite - Rarity hangs out with unsophisticated ponies and respects them. That is not superior behavior.
But then again this episode was realistic, which I liked. They didn't solve the crowd issue outside by wiping off memories, no, they simply let it go through them. Like they say, "Haters gonna hate." I also enjoyed how Toola Roola was in this, she has a great character design. And Pinkie Pie's part in the "Flawless" song was my favorite, mainly because she's my best pony, and it applies to so many parts in the fandom already.
