I saw it today...unfortunately, there was a screaming kid that people asked the parent to leave the theater with. Predictably, the parent got defensive and aggressive, ushers had to be called, and there was almost a fight.
That aside, there was a lot to like about this movie. Some really hokey dialogue in spots, and there were several things not to like about the last 10 minutes, but overall I thought it was way above the threshold for being worth the price of admission. Overall, I thought they blew through some seminal moments that really were worth thinking about and tied all the stories together and focused too much time on some other stuff not as important, but hey, it will get me to watch it twice to get it all probably.
Yoda was totally the shit in this movie (much better than the last one), I especially loved all of the scenes on the Wookie planet (I always liked Chewbacca), and I was pleasantly surprised with the job Ewan did. I still hate HC, but he wasn't quite so bad in this movie. The love scenes still sucked, but there weren't as many, and they didn't detract from the story like they did in II. I also really liked General Grievous.
Overall I thought B+.
As for 7-9, I've heard both extremes from multiple sources: 1) that he's completely finished and wants to move on entirely with the new Indiana Jones flick and other projects, and 2) that he already has the script ready and is officially scheduled to begin production in 2008. Not sure which to believe...but I guess that's what he wants.
