Prequels barely work in general.
Can people really come up with any prequels outside of SW that enhance the original?
The problem with most prequels, and generally any instance where a writer is tasked with expanding on details that were off screen previously (and ESPECIALLY in instances where the writer is different than in the original story), is that writers hate being predictable, even when being more predictable would benefit the integrity of previous stories, so they have a strong tendency to avoid directly depicting what is alluded to or implied in the original story and instead opt for an unintuitive alternate sequence of events that leads to the same place (though not always perfectly, which can causes inconsistencies).
The result is that prequels and expanded backstories are rarely ever as satisfying as the original implications were. Writers just aren’t willing to set aside their desire to go against the expectations of the audience.
