My thoughts on 3/15 were pretty much right on the money.
Obi-Wan, Palpatine, and Dooku got the good storyline, with intrigue, action, and Jedi confrontations. Anakin and Amidala got the implausible, poorly-constructed teen luv snooz-a-rama plot thread, though both tried quite valiantly. Christensen exceeded my expectations - he did a good job with the part. I thought he showed particular skill in translating some of the mannerisms and speech stylings of his predecessor. E.M. as Obi-Wan is just top-notch.
However, the plot, and the people (George, George - get back to the people, dammit), took a back seat to the pyrotechnics and CGI.
I won't even go into the whole thing. It would just take too long to write, it really would, but my frustration can be summed up by pointing out that the story is being painted in brushstrokes that are so large as to be crude, and insultingly obvious to the audience. It is sledgehammer symbolism, utterly lacking in subtlety and grace. It is frustrating, because there is a neat epic tale there, but it is getting lost because it could have been done so much better. Parts of it were good, parts of it were boring, parts of it were actually painful to watch and made me wince for the actors saying the cornball lines.
We did get to see the new Matrix trailer before it, though. ;)
