Agreed, they seem to have gone fairly easy on the shaky cam, but these snap-zooms are obnoxious. Takes you right out of the movie. I hate that sort of self-reflexive film making. This is meant to be fantasy and escapism and we are meant to be disembodied spectators. Why would any filmmaker go out of their way to make it seem as if there's a cameraman filming it? In shots that never even involved a camera no less. Boggles the mind.

Having said that, the trailer in general was very pleasing to me. You get the sense that our heroes are thrust into the adventure organically just as Luke was, and everything we see meshes aesthetically with the OT. The super clean troopers on that ice world was jarring initially, but I'm getting the sense that this new incarnation of the Empire is totalitarian, and cult-like rather than being the straightforward dictatorship it used to be. It fits for me.

The crispness of the image is always going to take some getting used to. As others have said though, it's 2015 and to be expected. Those 4K/imax shots do show some really nice grain though, which is an enormous upgrade from the overly scrubbed cartoon look of the Prequels.
