Well-put.
This "flavorlessness" is all over the story, and paired with the obviously genAI images is how I realized as I read that this was either generated or at the least deeply driven by AI.
It constantly described facial expressions, tones of voice, and other emotional cues in generic, dry terms that communicated nothing but the abstract notion of "this person felt a particular way about what happened and it's up to you, the reader, to imagine what that feeling was."
It felt very much like it was prompted to "show, don't tell," by someone who has no idea what that phrase actually means.
As a professional programmer with a deep background in literature and music, this is yet another example that if you aren't an expert in a field, you will get mediocre results at best from an LLM, while being deceived into thinking they're great.
No, I clocked the AI images before I noticed the text. I think the "obviously" is earned.
You are correct that a previous era would have included a bunch of Fiverr images that would be in sort of that style, but it's not the style that's the problem. None of the images say more than the text that they're illustrating. It's subtle, but once you notice the lack of information density it becomes starkly apparent.
