Good but still doesn't match any part of the original trilogy The blame falls solely on the shoulders of George Lucas for not employing others to direct this and his last three films while he stuck to the producing and writing.
I think that's why the original trilogy was so great. With Sith, George gets back to the business of what makes Star Wars so great but for a much shorter time than I expected. Through all the great reviews I saw, I expected a movie far above the last two which were pretty bad. But I got a movie that was slightly better than run of the mill mainly due to the effects, action and ever increasing connection to the original trilogy.
****BIG TIME SPOILERS START NOW!****** Things that made this movie great: Opening space battle, revealing the emperor early enough to give enough time for him to reign fire, Ben Kenobi's fight with Greivous, Any scene with Yoda, any time spent on Bail Organa's ship (reminding me Star Wars's opening scene), hearing James Earl Jones's voice, seeing Vader, Emperor, and Moff Tarkin (who was that clone of Peter Cushing?) on the bridge of Star Destroyer a la Empire strikes back.
Things that made this movie bad: Any interaction between Anakin and Padme and pretty much any scene that involved poor Natalie Portman whose talents were wasted in this trilogy (her death scene was more unconvincing than a 70's B horror flick), the long drawn out dialog, that went on way too long in some scenes, the cliché-ish "Nooooooooooo" that Vader let's out upon realizing Padme is dead (darn, even Lucas managed to make Vader seem cheesy), those ridiculous Viceroys taken right out of a Godzilla movie, and that ridiculous droid army Lucas insisted on having in all three films (they were the most useless characters ever - what the heck happened to 3P0 and R2?), Chewbacca's lack of involvement, the constant scene switching, and my disappointment with all of the special effects. Many were good but they cannot and will never replace real actors. Kenobi's big lizard was laughable.
***SPOILERS END HERE**** Anyhow, Lucas got my money and now that I know how it all plays out, I never have to see the episodes 1-3 again.
