What I really like in this trailer is the camera work. Or rather, the lack of camera movement (except at the end with things crashing down).
There are scenes were the camera just stands there even though someone is getting sucked out into space. THAT is how it should be. It really puts emphasis on them being by themselves, and of being mere little insects in the grand scheme of things.
I hope it's mostly like this, rather than someone running with a camera or shaking it every time something dramatic happens.
It's the right way to handle the camera in an alien movie: make it feel like you can only watch and not intervene. Like they are alone, separate from you, and there is nothing you can do about it.
