Lol I see what you're getting at, but I'd argue that those (incredibly fun!) movies seem "prophetic" only by the same quality that makes them relatable and profound:

They're inspired by history. Just one example being how the prequel trilogy bears heavy resemblance to the governmental structure of ancient Rome, before, like Rome, collapsing from the inside from in-fighting and profiteering in an attempt to control the whole Galaxy, before becoming basically like various monarchies throughout history, that almost succeed in ruling the world (galaxy) by monolithic force.

It's why Firefly was such a success, when it flipped and futurized the American civil / revolutionary wars concept. It gives us something familiar enough to attach to, with twists that make it unique.

Edit: I welcome historians to correct any errors in my rather generalized understanding of history. I tried to get the point across while resisting research rabbit holes. ;)
