I'm not one to go out of my way to defend the PT, but they get a bad wrap. I realize it's absolute sacrilege to say so, but I like ROTS better than ROTJ. It's just such a dark film and there's plenty of emotional moments. Plus, you get to see a lot of the cool, lesser recognized Jedi in action, like Ki-Adi Mundi and Plo Koon. The lightsaber fights are among the best in the entire franchise, Hayden's acting is much better, and imagine how much better the movie would have been if they went with Padme's original ending instead of what we got.
Whereas I think ROTS is a great SW movie, everything, EVERYTHING about AOTC is miserable. EVERYTHING. Obi-Wan vs. Jango was like the only good part until the Battle of Geonosis. Movie is absolute trash and Hayden and Natalie alike are terrible.
I've always felt TPM would actually be a pretty worthwhile movie if not for too much Jar Jar and if the podrace was exponentially shorter, or just entirely removed. Jar Jar is at his most annoying on Tatooine, if they just kept him on the ship with Obi-Wan during that whole sequence, he would have been a much more tolerable character, as his character actually does have a big storyline moment when he unites the Gungans and Naboo.
The podrace though. I literally can't watch it. I change the channel or skip the scenes on the DVD, every single time. I don't think I've watched the podrace in ten years.
One of the cool parts about the PT, like it or not, was seeing more of the Star Wars universe. In ANH, all you get is Tatooine and the Death Star, and a few minutes of Yavin IV. In ESB, you just get Hoth, Dagobah and Bespin. ROTJ, Tatooine again, Dagobah again, the Death Star again, and Endor. The PTs open up so much more imagination with worlds, like Kashyyyk, Coruscant, Naboo, Kamino, Mustafar, etc. It's great seeing so many different environments in my opinion.
Again, there's good and bad with the PT. It just depends on what you're willing to overlook and how much you want to let some things distract you from Star Wars as a whole.
Just my two cents.
