Getting the criticism out of the way first: yeah, it does feel like the festival is just there as just a device to allow for a situation to have a person that Rarity admires to come to Ponyville. We could have done more with the Ponyville Days festival, especially when it comes to things becoming chaotic due to Rarity being more focused in impressing a traveling writer than doing her job. Still, you can see why Meghan McCarthy considers it to be the "her favorite Rarity performance ever", as she pretty much goes nuts in an attempt to attract Trenderhoof, with her completely losing by going completely "hick" (and Applejack countering it by imitating Rarity). Probably would have worked better if the festival aspect was handled better (i.e. keep it simpler by not including it or actually showing the other ponies preparing for the event alongside Rarity trying to impress Trenderhoof), but it was still a hoot.
Comments:
-Getting some Dinky love early on in the episode, as she shushes a hyper Pinkie Pie.
-One example in terms of how the Ponyville Days festival events could have been better incorporated in the episode: given how Twilight and Fluttershy were assisting in the fashion show, they'd probably could have been more involved in the climatic bit that involves auditions for the event (either assisting in the audition process or assisting AJ in her plan to get Rarity back to normal).
-Is it just me, or did the episode definitely go nuts making AJ attractive? First, there's the image of her as she's harvesting apples that causes Trenderhoof to fall for her, and then
this shot.
-Loved the irony of Rarity telling Spike of her situation about how the one pony she has a crush on has a crush on someone else.
-Derpy not appreciated? Not in the minds of the MLP fandom.
-In terms of the poem that Trenderhoof recites, wouldn't it have worked better if the second to last line rhymed with Rarity? To me, it looked like the last two words in the poem were going to be Pinkie Pie.
-Not sure if it was a good idea to spoil the climatic moment of AJ acting like Rarity in order to get her back to her normal self, but it mean I know when to crank up the volume when Rarity delivers the "I LOVE BEING COVERED IN MUD!!!" line.
