I can understand the weariness for this, but these images actually make me feel much better about the movie. The cast just looks great, and while they're young...that is kind of the point. I'm willing to ignore details like supposed character age, etc, as long as the overall look and feel is handled well. So far, it seems to be.
As for the bridge, I think its beautiful. Its a perfect retro look without being a direct copy, which would be pointless and look silly. The fact that it keeps so many bright colours, hell the chairs are still red in a couple of places, really adds to the effect. The screens are great, with the kinds of designs one would expect even if you don't know what they are. They've got that bright, retro feel to them while still looking like something that would actually be futuristic.
