I personally prefer the idea of the story of the prequels than even the original trilogy. I think the original was a classic, but it was rather simple in scope. The farmboy takes up the sword to defeat the evil king. I enjoyed the political nature of the prequels and how they delved more towards the descent into fascism and how power can corrupt. It seemed to give the Sith more weight because they had ambitions rather than just being evil and in control.
I do feel that the execution wasn't always that great in the prequels and there were a lot of things wrong with them. But I think that even despite those flaws, they were a strong trilogy and at least were ambitious.
Yeah, as you could tell from my post, I completely agree.
