I thought this was an interesting episode. There was lots of great comedy and heart, and it was a perfectly character-driven plot if I may say. I especially enjoyed the focus on Applejack & Rarity.
However, I do think that the way everyone is interacting with each other needs to be toned down a little bit. It's nothing personal, but, there were certain things about the way each character interacted, such as Rarity & Applejack, that made me a little uncomfortable, and it made me wonder if Confalone is forgetting that everyone is supposed to be friends and nothing more. I have felt the same way with some parts of "Forgotten Friendship" & FiM's "The Break Up Break Down", as well as the book series written by Michael Vogel & Nicole Dubuc.
My only other issue comes in the form of Vignette Valencia.
As a villain, she just wasn't very original, new, different, or fresh. Like the other villains, I enjoyed how she was made as an individual character, especially her personality & comedic timings.
But...
Overall, how she came out, and the outcomes with her, especially what her intentions were, and getting reformed in the end...
Well, it gives you the feeling that it's the same thing over and over again, and it kind of makes me think that a brony like me can do a lot better than the actual show staff when it comes to storytelling & villains.
In the end, "Rollercoaster of Friendship" was at the most a rather neutral episode for me. In a way, it has a certain sense of fun about it, but...it's literally the weakest of the EG episodes. One of my least favorites, definitely.
