Funny thing is, I remember when some people thought Cloning as a technology was "Too Star Trek" for Star Wars and therefore had no place in continuity.
Since cloning was mentioned by implication early in
ANH, I don't see the logic behind that. What tech is or isn't "right" for
Star Wars depends on what tech
Star Wars shows. You might as well say lightspeed is "wrong" for
Star Wars.
However,
Star Wars does have (or should have) more of a mystical rather than technological focus which is why it makes sense to limit the sci fi gimmickry, for instance, for what time travel exists to be visions courtesy of the Force rather than setting-the-timeline-right type Trekkian jaunts.
That was kind of the point behind the Republic though, thought it was clearly depicted in the prequels as an old institution having grown too large and ineffective to govern and protect it's citizens.
I did notice something along those lines, but it was pretty half-heartedly done. I didn't see anything that convinced me that the good people of the Republic were all in mortal danger, and I didn't get the idea that Lucas was trying to convince me that he thinks totalitarianism is a great option if a society's safety depends on it (and given what I know of his politics, I wouldn't expect him to try to make this argument - but there's no reason his movies need to follow his personal politics.)
For this to have been the actual premise of the PT would lead inevitably to the idea that Anakin was
right to choose the Dark Side as a viable option to the corruption he saw around him, that endangered the lives of billions, and Anakin would have had to have been depicted as being right, not as a tragic figure but as the true hero of the story.
When he blew up Alderaan later on, for instance, that was just acceptible losses, defending a political system that in balance was necessary to safeguard the lives of trillions of beings. The rebels were a bunch of childish idiots who didn't understand how things need to work, and when they overthrew the Empire, they endangered the lives of trillions through the chaos they left in their wake.
All this certainly would have cast the OT in a whole new and possibly very interesting light, which we really would have needed to see a sequel trilogy for, and since I want to see the sequels, I'd be perfectly happy with that. If the old Republic was so corrupt and incompetent that totalitarianism was preferable, then the story isn't finished till we see how Luke and Leia manage to fix whatever caused the problem with the original Republic and not repeat the tragedy of the past. Or maybe they do repeat the tragedy of the past. Also,
ROTJ's ending would need to be re-shot, because the idea that Anakin dies without Luke ever realizing that his father was a hero who didn't
need redemption is a pretty lousy way to end his story.
But if Lucas really wanted to indict the Republic, then he needed to stop trying to depict Anakin as a poor, pathetic dupe of Palps and rather depict him as someone making a perfectly rational choice even though he'd been on to Palps for a long time. And Obi-Wan would be revealed as a villain for trying to stop Anakin, and mangle the poor guy in the process, when he was just looking out for everyone's best interests, but had to battle the moronic Jedi who were mindlessly following the orders of a degenerate Republic and standing in the way of progress.
All this is entertaining to discuss but I think it's way too out-there for
Star Wars, which really should stick to a far more simplistic level - simplistic in a good way, meaning like mythology, not meaning dumb and poorly thought through. The Republic should be basically good and functional. Anakin should be a great hero with that one fatal flaw that brings down even great heroes - hubris. He's not pathetic, manipulated, or too stupid to save himself. Lucas just needed to pick a GOOD plotline and really go with it instead of flail around with a bunch of half-baked notions that didn't add up to bupkis.
