AOTC should have been the clone wars series and the romance of Ankina and Padme but actually good. And He should have already been falling to the Dark side in that one.
*sigh* there is just so much. Padme should have lived on Alderan not Naboo. And she shouldn't have died in ROTS. Qui-Gon should have been Mace and not have died. Yoda should have never touched a lightsaber-he was too powerful for that kind of stuff.
