Like all SW, love the mythos, ADORE the KotOR games. Hey, he led to the KotOR games! How can we hate him? (Okay, so your mileage may vary with the sequel, but I thought it was okay)
Yes, the prequels were kinda worse, but I like watching them. They're shamelessly epic, downright campy at times, they tie in into the mythos like the OT's idiot friend that everyone wants to watch make a fool of himself. And while 1 and 2 are complete duds in terms of drama, Revenge of the Sith actually had some pretty effective conflict.
Yes, the acting in 3 sucked (who'd figure that James Earl Jones cannot make a good Big No?) but I think it was better at starwarsing than Return of the Jedi, it was more epic, more tense, it had better music, better fights, bigger events, better conflicts, etc.
Now, I think everyone agrees on this - the prequels had some KICKASS music, amazing lightsaber duels, awesome villains (Maul, Dooku, even Ian McDiarmid chewing the scenery was a delight to watch), gratuitous but generally very good special effects, and so on. They were made so for the wider appeal, and it worked by the looks of the box office. Much worse movies have reaped the same amount of money, like Revenge of the Fallen, so being angry at Revenge of the Sith for being just enjoyable sci-fi adventures, not world-shattering epics, makes no sense to me.
If anyone really wants to get deeper into the story and the characters, which the general public and 95% of the audience that went to see the prequels DON'T, they have the novels, the video-games, the roleplay games, the ridiculously detailed expanded universe, etc. I'm not sure whose loss was it that the movies were blockbusters. The earnings and the popularity allowed dozens of other SW-related products that were actually good (like the aforementioned Knights of the Old Republic, the Sixth Sense of gaming).
And yes, Jar-Jar sucks for everyone, and so does the Holiday Special ("Stir whip stir whip whip whip stiiiiirrr," oh the horror...).
Off-topic, I hope How to Train Your Dragon is on the list of reviews in the near future. Doesn't have to be next week. But pleeeeaaaase, Movie Bob!
