Bingowings, I like your idea of "reversing" the story of TPM, I think it would definitely make the story more to the point. I'm just not really sure it could be accomplished.
The main problem is that in the movie as it is, we care so little about the people of Naboo: we are being told they are suffering and dying, but we don't see it. The only thing we see of it, is through Queen Amidala's eyes, she is our only connection to the invasion. I think taking out that part of the movie would really hurt what little we care about the planet.
I also think that starting the movie on Coruscant would really bog the movie down in politics at too early a point.
I do think the idea is very interesting though, so could you elaborate on how you would have it work?
