Things I liked - decent pacing to the movie, I never got too bored. Several key points to the overall story get addressed, which was cool - since Episode 3 is the only remaining movie it becomes more clear how we get from Episode 2 to 4. It's just plain fun getting back into the Star Wars story after not thinking about it for awhile.
Things I did not like - I'd thought Jar-Jar would only be in it briefly; he was in it for ~8-10 minutes, which was 8-10 minutes too long for me... The writing still was not as good as Star Wars or Empire Strikes Back, or perhaps I'm older and more critical, perhaps both. I'm being a bit picky here - I did not like the cgi Yoda. He was so engrained in my mind as a puppet/however they did it before, and now they try to do a lot more facial expressions and physical movements that he's never done. Just did not feel like the same guy to me, and that was a bit disturbing.
Don't rush out to see this one, but do see it in a theatre sometime. My .02.
Regards.
The reviews are mixed there. They are arguing about "mistakes"... but the die-hards love it.
