I don’t object to Starlight focused episodes (not anymore, S7 made the character finally click). I love that we get to see Trixie recurring through her. I like Starlight’s quirks and her dynamic with both Trix and Twi and Sunburst.
But for a character that has been introduced and positioned so prominently, the fact that she has no relationship whatsoever with five of our protagonists is not great.
Specially when some of them don’t get that great character focus to begin with.
And there are a lot of secondary characters with little focus that would’ve been nice to see being thrown a bone to shift focus and spread things out.
Starlight is fine for this, but she got shoved so hard that not everybody could get on board with her inclussion.
Some people are unreasonably harsh on the character, for sure.
Not everyone that has problem with our new mane character does for no reason, however.
