for the last time

No way, Rochester. Episode III was hot.

I hope you're not basing your opinion of the entire movie on the perceived degree of "chemistry" between Padme and Annakin, but so many other parts of that movie kicked so much ass.
Everyone will stipulate that the writing is truly terrible. However, the writing in Episode III was certainly less terrible than in Eps. I and Deuce. And lest we forget, the original trilogy, which everyone seems so hot on judging these films against, had some pretty awful lines as well. ("I knew there was more to you than money!" Feh.) Word is that Tom "Shakespeare In Love" Stoppard had an uncredited role in punching up the script this time around. Lucas' influence still trumps, obvs, evinced by the inclusion of Padme's weak-ass soliloquy. "Hold me, like you did on Naboo... before there was war..." Ugh.

So, let's not make too big a deal out of the writing. We all knew it was gonna suck. I will take issue with your assertion that Hayden Christiansen can't act. Did you see "Shattered Glass?" Lucas has also said that whiny Skywalkers is a trait he purposely wrote into the character. HC had a tough role, too. He had to build on the whiny-kid from Episode I, and also start to try to incorporate some of the characteristics we see from Vader in Eps. IV-VI. It's an awkward balance for any actor, but keeping these challenges in mind when re-watching Eps. II and III, it's clear that HC isn't really so bad.

Natalie Portman, however, has no excuse. Yeah, she fine. But, she is one of those actors that does the same thing in every single movie, and she deserves no respect for her acting in these films (outside of her delicious petulance as Queen in Ep. I).

Oh, and General Greivous was busted. So, he leads the droid army, but he's not a droid? Or is he? I mean, he has a heart? Wha...?

Again, I think people had unrealistic expectations for these movies. Yes, Lucas sold his soul. But judging them independent of the original trilogy, Episode III is by far the best of the prequels. I mean, there was like a dozen lightsaber fights. Come on.
