9. The Timeline Should Have Been Pushed Back
In the original films and in the Expanded Universe, it always seemed as if the Clone Wars were some kind of ancient conflict, that the Empire had been around forever, and that the Jedi were some kind of long lost order that no one really remembered. However, in the prequels we find out that there was only a 20 year gap between the clone wars and extinguishing of the Jedi, and the start of Episode IV. Really, 20 years isn't all that long and makes it seem odd that everyone in the originals talked about the Clone Wars as if they happened a long time ago. Pushing the Prequels, or at least the Clone Wars part of it, back about ten or fifteen years would make the continuity between two series seem a little more realistic.
