Didn't see your reply.
There's quite a few but I don't think it hinders the experience that much:
The other anon mentioned fight scenes. They mostly feel like clutter to fill between plot point A and B. It seldom holds any weight narrative wise. All the soldiers and robots especially just seem like an excuse to put action on the scree, and it's kinda boring after a while.
I don't really like the way how story beats are handled.
Most of the time the story revolves around some sort of mcguffin the protag needs to find, and almost all of it is First One's tech.
You can argue that this is to enforce how important the First Ones in the world, but the amount of times Adora and the gang needs to retrieve some First One artifact is a bit much.
Princesses have fun personalities, but for most of the time they just seem like background noise. I don't really get why they needed so much screen time.
Also, if it wasn't for her VA, Adora would have been somewhat boring. I feel like she pretty much the same throughout the whole series.
