I fall into the "Yes, even though I don't like them as much as the originals" category. I always felt that it would be a shame if they were never made. Now that they have been they certainly don't measure up to the originals, but then they definitely do have a very different story to tell. Were I in Lucas's shoes, I would have done certain things differently: no Jar Jar (at least not as we know him), no pod racing, no Anakin as a child, no midichlorians, Anakin and Padme would not ahve been so wooden in AotC, and Darth Maul would have been given more lines and I probably would have kept him around longer than one movie. As a matter of fact, I think they should have condensed Ep1 into a 15 minute prelude to Ep 2, made the Clone Wars into Ep 2, and then left Ep 3 where it will be. I would have worked in Yoda lightsaber fighting, but I wouldn't have had him be the one to pull Obi One and Anakin's fat out of the fryer (I would have made it just as grim as the ending to Empire Strikes Back).
Having said that, there are many aspects that I do like. I agree that some of the best lightsaber fighting was against Darth Maul in Ep.1. The action sequences in Ep.2 weren't at all bad. I thought that bringing us the all-out battle at the end of Ep. 2 was also highly entertaining. I like the fact that after reading about Coruscant for many years, we finally get to see what it looks like. In fact, the fleshing out of the universe, delving into the populated areas, and having a very politically driven storyline greatly appeals to me. Lets face it, the fact that it was Jar Jar that sells out the republic to Palpatine in Ep2 almopst makes that character worth watching in Ep1.
The explanation of the clones was worthwhile. The fight between Jango Fett and Obi One was clearly one of the highlights, and its also very cool to see the role that Boba Fett plays in the larger story. He is far more central to the story than most had previously guessed.
Seeing more than 3 jedi in the entire trilogy is another very cool thing about the prequels. We get to see the jedi order as it once was. And then in Ep3, we get to see how it gets destroyed.We get to see the various aliens that made up the jedi order, we get to see varying fighting styles, and we get to see a major battle involving a bunch of jedi.
All in all, the prequels aren't that bad. They're just missing the special magic that 4 - 6 had. I miss having a rogue as one of the main characters, I miss the rebellion storyline and I miss the theme of hope in the face of overwhelming odds. Of course, given the subject matter, its not lie much of that could have made it in.
So there! Glad you asked?
