You are making no sense at all.
Or do you honestly believe that today's audience would accept a vision of the 23rd century as seen through the lenses of 1966?
The visual aesthetics you would like to see are those of the 1960s.
I wish I remember which thread I replied to this in (maybe TECH?), but the visual aesthetics of the 60s are in some ways still very futuristic looking. RE-interpretting that design aesthetic is one thing, something I'd be cool with. Pissing on that design aesthetic doesn't work for me. And what I'm seeing inside and out reeks of urine.
I don't object to ST-One's comment, because I know where he's coming from. He's not a fan of TOS... he's a huge fan, however, of TMP, and sees that as "the yardstick." (Am I misinterpreting you, ST-One?)
That's very well-represented by this design. It looks like a combination of 1950 fender-design and the 1970s TMP Enterprise. It does not, however, look in any way like the TOS Enterprise.
It's a fine design for a contemporary ship launched during the TMP era. And the sets and ship design clearly represent that 1970s design aesthetic.
But the 1970s are no more "contemporary" than the 1960s are. Both are a number of decades in our past. At least in the 1960s, most of the folks working on the TV series had some military service under their belts and many had served on real-world naval vessels or had worked with real aircraft. Thus, most of the stuff in TOS had the feel of being "real" (multi-color gels using for "funky technicolor lighting" being the main deviation from that, of course).
**********
The 1970's TMP ship was better in quality, but did not feel like a place where I could imagine actually living. It was too artificial, too mechanical, too psychologically uncomfortable. The reworkings for ST-TWOK and later didn't dramatically change that... though TNG did (until Generations, that is).
A ship is a place where people live and work. And humanity isn't going to change very much over the next several centuries (at least in the Trek world we've been shown!). That new bridge may look "kewl" but it would be an unpleasant place to spend your days... the lamps shining in the faces of the console operators being just one of many issues. It's not "modern." It's just BAD... couched in the cloak of "wouldn't this be cool" without thinking "WHY would it be this way?"
******************
The exterior changes... well, I can see why they might have done a few of them. Reinforcing the neck is hard to argue against from a technical standpoint, for instance, so if that was the only major change, I'd have no problem with it. The elimination of the saucer "undercut" is hard to argue against (as anyone who's ever tried to figure out a valid reason for "why" would probably agree with).
But those nacelles? God, but they're goofy. They really do look like a graphic-artist-wet-dream-gone-haywire. The secondary hull no longer looks like a hull on a naval vessel, but instead a clay sculpture... more like Moya than like the Enterprise. And it doesn't even seem to match the primary hull (which does look, at least, very mechanical in nature).
****************
It's not a bad-looking ship, but it's not the same ship... and the changes weren't made (as far as any of us know) for story-driven reasons, nor for any REAL technology-driven reasons. They're made simply for "personal taste" reasons... and for no other reason.
If the TMP ship doesn't look "dated," when it's thirty-plus years old... why would you say that another ship made just a decade before that is inherently "ancient and silly?"
