To be fair, she probably only watched the movies once, when they first released. And she may not have even watched TRoS. So she’s not really in a position to go into further detail on them, and that’s not what she wanted to focus on here, anyway.
Jonathan Rinzler said in an interview on YouTube that he spoke to Marcia in the summer of 2018 or 2019. I can’t remember which. It was before The Rise of Skywalker was released. Not that it’s relevant as I agree that wasn’t her focus as she only gave broad strokes to her opinions. Like when it came to The Phantom Menace. I don’t see how some take her words to mean she hates it. To me it seems more like she was very disappointed by it and didn’t like a number of aspects but didn’t hate it like she did with the Sequels. I could be wrong and I don’t want to speak for her but that’s at least the impression I got from her words.
