i think its clear that the TOS era was marked by a relatively short-lived dalliance in 1960's modernist styling, with little impact on long-term design and aesthetic trends.
No. If you look at other sci-fi productions and sci-fi hardware of the time they all had a very similar aesthetic. In terms of having a clean look. And it's a look I still very mich prefer to some of the overdone detail following in the wake of Star Wars.
Don't get me wrong---lots of detail can work within context of a given work, but I find it odd seeing it applied to Star Trek.
Even TMP got more detailed than TOS (understandably), but it still wasn't in SW territory.
