Hmmm...
For ship models? Almost. 1701 TMP is a a glorious redesign that has withstood the test of time. TOS1701 is a trendsetter, but the 1950s curves on the hull date it. And yet, when 1701-D for TNG came out with all the windows and a convex saucer design instead of concave, that won me over despite the sleek, sharp look of 1701 TMP (and 1701-A).
1701D looks awesome on the big screen. A shame that the triple-nacelle dreadnought refit didn't make it to the big screen...
...but 1701-E is easily the best looking ship ever, merging 1701 TMP's sharp aesthetics with 1701-D's grander nuances. Despite the bizarre rehash of the 1701 shuttlecraft bay in the lower aft. And despite the TNG movies that use the 1701-E being less than rewatchable in my opinion
For sets? No way. Well, TMP's flickering monitors (a couple dozen rear projectors!) haven't fared well, but II-VI have a clean, militaristic look. Nice corridors as well.
TNG did re-use TMP corridor sets. And built their own (beige, of course.)
The 1701D bridge revamp in Generations looks great with the subdued lighting. Shame the follow-up movies would go back to beach blanketed lighting.
TSFS's Excelsior bridge looks bizarrely like one elongated wall, with neon green highlighting that hasn't dated well.
Why did FC have a hologramatic viewscreen appear on command, but in Ins and Nem the viewscreen reverted to a basic format?
For uniforms, easily:
TMP's pastel outfits, missing only comic bunny ears and a puffball cotton tail to really sell the effect as completely and as unintentionally as possible, are well-described. I agree with Armus above that Kirk's admiral outfit easily fares the best of them all - good style, great colors, did return for a new movie (loosely retailored and not for homage, certainly given TMP's reputation for its pajama partywear), shows off the least amount of "package padding", et cetera. But any of the other outfits? Like the beige suited dude on the bridge or Decker in Engineering or Rand and Uhura anywhere? Why not just invent "invisible uniforms" like what the Edo wore in TNG and be done with it?
II-VI also have a very stylish and big-screen and big-80s look, but "practical" just doesn't come to mind no matter what fabric type is used. No military in real life has ever had so much shoulder padding. Ever. Or maroon because, as we all know, the troops should never blend into any surroundings and the best color to ensure that is any hue of red... then again, TOS and JJVerse are trapped into branding though at least TOS came out when color TV was new and they wanted to show it just like most mid-60s TV shows had.
Generations does DS9.
FC-Nem set a new trend with functional looking outfits, even if they're largely black and gray. They've grown on me, though in the 1990s I felt they were just being lazy.
JJVerse - the Admiral outfit aside, they're just copying TOS-Technicolor as the color scheme is just iconic branding. I did like the revamps in "Beyond", didn't Spock wear a gray jumper with red highlights (as opposed to science blue?).
For stories?
TMP, and Ins, Nem, ST09, STID all are a little too derivative despite a number of scenes I liked. Especially STID as I liked it more than Ins, Nem, and ST09.
TVH is arguably even more dated, not because it's derivative of too much past already-done material but because it's taking place in the smack middle in the 1980s. Cars, product placement, donut shops, big hair, personal computers, it's all there...
TSFS is a runner-up with big-hair all over the place. I'm surprised nobody fainted due to the fumes from all the cans of hairspray... especially on the Genesis Planet once the pyrotechnics were ignited...
Fortunately, the 1990s in general having no style means there's not as much of the TNG movie crew that's going to look dated or locked to certain era. It's just universally bland. Not sure if that's better or worse. CFCs aside, of course...
