Okay, just watched the trailer a good dozen times. I'm not going to spoil any specifics, just give my reactions to the overall effect it had on me.

First of all, I noticed a lot more JJ-isms such as extreme closeups and a few lens flares. Dynamic camera, very in-your-face stuff. It felt most similar to 2009 Star Trek in style, and though that style worked for the Trek Reboot, I don't think it works so well for a continuing story, especially not Star Wars.

I liked a few shots in the first seconds of the trailer, one in particular screamed classic Star Wars and gave me hope for more in the film. but most of the rest of the shots could have come out of any big budget action film of the last several years, for all the effect it had on me.

The colors feel off, as I think JJ prefers a more saturated look than exists in any of the OT films. He's definitely not out to recapture the look of the originals, so I wonder why he even bothered to shoot on film. All in all, it was a disappointment.

One bright note (haha) is the music. If nothing else, we get a new Star Wars soundtrack from the Williams, and that alone is worth the price of admission for me.
