Basically the Bronies and pretty much a lot of MLP fans

So when it comes to Bronies and pretty much many of the MLP fans, a lot of them prefer MLP as an episodic series that focuses more on it's friendship morals with a little bit of lore before it later became more serialized and focuses more on it's lore, goes bigger with it's antagonist redemptions, and development on side characters (such as Starlight and the Young Six) and then G5 continued the status quo that the later Seasons of G4 were focusing on.

The Brony fandom was more relevant during the early 2010's when the series was mostly episodic, had only very few antagonist redemptions, and most of the side characters being plot devices, and then a lot of people stopped watching the series because of it trying to be too deep with depth, lore, and character development.
