Spike episodes were a total train-wreck since you have to drag everyone else down if you want him to shine at all. So, Jayson Thiessen and Jim Miller undoubtedly screwed up Lauren Faust's show... They didn't do their job right — supervising the writing and everything properly, which is why someone else should've taken their place after she left. 

The show had other mistakes here and there, though, which could've been done better. And the quote is: "What's done is done." 

Speaking of Jayson Thiessen, I stumbled upon a Reddit user named "imtrappedinabox" - according to this screenshot - who asked him: "Humans? Please tell me that you won't add them at any point." And he answered: "Heavens no!" And here's my question: Why not? F*cking fascists... 

It's a disappointment is that humans - particularly Megan, Danny, and Molly - and mythological human-like species didn't return in the later incarnations of My Little Pony after G1... It's understandable that it's due to people's - particularly Lauren Faust - personal tastes, though, but still. After she left, Jayson Thiessen and Jim Miller could’ve added them later on, but no — they chose not to for her sake... Either way, none of them returning in G4 - and the other incarnations of My Little Pony - was a letdown... And, of course, it's always preferable that they returned right away in their debuts. Megan, Danny, and Molly would've been perfect protagonists alongside the Mane Six in G4. 

Speaking of mythological human-like species, Tirek didn’t resemble a centaur at all. He doesn't have a human face. Seriously, why did they remove the human parts on every mythological human-like species and replace them with non-human parts? Not only is this idea weird, but it’s also silly and pointless.
