Since the plot and the continuity and the acting and the music and the special effects have all been discussed to death by people far more learned than myself, I choose not to discuss them. Instead, I shall explain why I found this movie so loveable - the mistakes.

A trivial fact, certainly. An intentional injoke? I think so. But useful to impress your friends with. Now if only Anakin had called Padmé "Natalie.."
