Haven't we always done that, though?
I was expecting that And yes, we did. Raymond Loewy was a brillant designer and as important to industrial design as the Bauhaus movement for architecture. He started that trend in the IIRC 30ies?
But look at the reason for the designs. The need for more speed. But Movie vehicle design needs to evoke emotion and has to be interesting to the eye, bring across a feeling of agression or grace or strength, creating instantly recognizable shapes. McQ and Johnston and Cobb and Reynolds and Mead all did that. There is always something breaking through a streamlined hull (see the streamlined train engine), making it interesting.
The NuBSG Vipers are a good example, although the classic design was streamlined as well, but IMO done in a good way. Enterprise? Bad. X-Wings? A catastrophe if not for the old designs by McQ, borderline IMO. Stormtroopers in the ST? I think that whatshisname totally missed the point of those uniforms. Where is the intimidating skull and skeleton appearance, the shock in shock white?
