I loved the Enterprise! The first shot of her in space (which I guessed would be the first after the pic we got of her last year) was absolutely stunning. No need for an introduction, she IS the U.S.S. Enterprise.
I love the interiors as well, even the lower decks, for the most part. There were only a few moments when the 'brewery" sets bothered me, but it was only a minor occurrence.
Did anyone else notice the moving parts on the exterior of the ship? The "fins" on the back of the nacelles split apart into four or five sections and extend up and away slightly from the nacelle when going to warp, and the "warp coils" glow bright blue underneath. Its subtle, but a really cool effect I think. It sells the idea of these as powerful machines, and adds another layer of motion and dynamism.
The main Deflector also has pulsing points of light or something. Its hard to describe, and I only noticed the second time I saw the movie, but there is definitly motion to the deflector. Its another subtle effect, but I like it.
