That was a nice little taste. I dig that they used real actors; hopefully that means the characters move like real people, rather than the marionette-like trash we still see in so many AAA games today.
As far as not telling us much, I agree and disagree. We learned a bit more about Ripley's motivations, which was nice. I'm definitely getting a Prometheus vibe with the whole "still searching for answers" angle, even though it's certainly not on such an existential scale.
