Only one for the trilogy? Jedi Rocks. I can live with people not thinking Star Wars is the superb trilogy it is. But I can’t live with people hating Star Wars, which is exactly what Jedi Rocks makes people do.
Can I do one per movie in the OT? Jabba, Alert my Star Destroyer, and Jedi Rocks.
Can I also cover TPM? Then restore the original podrace.
I don’t really give a damn about the rest of the PT or TFA’s changes.
