So far I love everything I've seen. The uniforms look fantastic, I can very much buy the character looks, and if the U.S.S. Kelvin is any factor, the Enterprise should look fabulous.
The bridge is clearly altered, but I rather like the update. It looks like something different. We've been force-fed such standard looking control stations in past films that this set really does feel like a breath of fresh air.
I've had a lot of faith in J.J. Abrams since this movie was announced, and I hope my faith and patience pays off. I like what I see. I hope this is the film to put the magic back in Star Trek.
