Well, it could have been worse. Some of the love-interest acting wasn't hot ... but it was better than Episode II. And a lot of the action was pretty good.
I did feel as though they tried to cram a lot of plot wrap-up into the last few minutes of the film. It's the same feeling that I get at the end of some sci-fi and fantasy novels -- as though someone ran up against a deadline. But then again, the epic scope of it all almost needed this kind of wrap-up.
You won't be stunned ... but you probably won't be disappointed.
