Sorry, late to the party with the holiday and stressful week.

No real complaints here. It has a bit of a modern take on a 1970s film look, but I'm ok with that. In the prequels, Lucas completely disregarded the look of the 1970s (along with several other aspects of the original films) and set out to devalue them.

Here it looks like Abrams is at the very least trying to play nice with them. As mentioned earlier, some of it could also be that these are early versions of the footage and not processed to the look of the originals yet. We are, after all, over a year away from the finished film.

The only Abrams-y thing that jumped out at me was the Falcon flying around within an atmosphere. That all looked very much like the shots in 2009 Star Trek where they're controlled-falling on their way to disable the drill. Again, not a complaint just an observation. Similar in-universe situation (ship in upper atmosphere of a sunlit planet), so it should look similar.

The low flying X-Wings looked and sounded wonderful. Best part for me. In the end, the teaser did what it was supposed to do. Gave me a glimpse of the film, served as an update and first look at footage, and it made me want to see more.
