As I posted in the other thread, I have mixed feelings. Some things I like, others I didn't, much I don't either like or dislike. The closer I looked, however, the more I liked what I saw. It seems there has been much attention to detail, including making things look used. I don't have much of a problem with the silly-looking droid, as long as it doesn't end up being the next Jar Jar. Camera shakes and whatnot are more a product of modern movie-making rather than J.J.'s personal style. I didn't like the voiceover much either, but naturally, that isn't any indication of the final product.
I'm neither excited nor disappointed by the teaser. I expect the movies to have their own style distinct from the PT and OT, but keep true to the OT in some aspects, while not ignoring the PT at the same time. I expect to enjoy the movie, but I think it's safe to say that it will not be a classic. The OT was classic, and it just cannot be done again within the same saga. The expectations and level of cynicism are too high nowadays, and it would be extremely difficult to capture the same balance found in the OT without being accused of copying the OT outright.
