I guess nobody in short-attention-span-theater, which explains why they changed the ship design too.
I guess if I wanted to see the same thing twice, I'd do something really unusual and buy a model kit of it ... ohshoot, no, there are lots of people who buy models kits of something and look at it again and again.
It's context, man! You can do spaceframes in a million different ways, most of them damned interesting visually, and avoiding the rebar-look of ground builds.
Everybody talks about antigravity as if it is a given, and we've seen little to suggest that. The antigravs in TOS were a little handheld rig in OBSESSION. We don't know how the shuttlecraft 'boosters' work, or if they use a/g at all in TOS time. There are obviously things that keep the crew from liquifying under acceleration -- OUT IN SPACE ANYWAY -- but forces on ground are different, and ... shit, TGT is right, you guys won, so that means TOP GUN is the smartest movie ever made and TITANIC the most moving. Up is down, wrong is right ... and trek looks to now be fantasy (as in shit), not SF.

People are taking this whole thing way too seriously. Because the ship was built on the ground...it's fantasy. Yep thats the deal breaker, because nothing in Star Trek before has ever EVER come so far from scientific fact as the ship being built planet side. Damn, I guess I have been watching a different franchise all these years.
The ship has artificial gravity, which means Starfleet obviously has technology, reliable technology, that can change gravitational forces, and evidently some variant of this technology is employed here.
I love how for years, ever since TOS was created, people have sat and tried to justify, and figure out what we see in the shows in a technological sense, how it works, why it works etc, and why things may act differently then they would in the real world. Yet no one really knows how it works, because it was all made up. Yes, most of the time the concepts are grounded in a real world theory, but thats all.
So now this movie comes along, and we see something new, and no longer do people do what they did before, and try to figure out why, and how something was done in universe. Now people just sit and whine because it does not match something in the fanon explanation. TOUGH. The shows creators from DAY 1 have done things how they want, when they want, and if something is scientifically plausible, AND good in the story, they use it, and if it just makes a good story, but is not really realistic, they also use it. THATS WHY ITS SCIENCE FICTION. For years, the other producers and directors have all gotten slack for it, and yet now when Abrams, and new people do something, people just call it shit. Oh well, don't see the movie then, because I figure the audience that will make or break this film is not the audience going "Damn, I wish that the ship was built in spacedock."
And thanks for mentioning Top Gun and Titanic, because those two films were something that Trek has not been in a while...successful.
