Agreed - buttt that logic applies to the model. Not the design.No, the argument is that it was made in the 1960's using 1960's techniques on a 1960's budget for 1960's sci-fi expectations. It looks cheap, it looks under detailed (which no amount of textures can fix) and it looks simplistic.
Hence why the movies used a refit as an excuse for not bringing the model back.
The design is as futuristic as it ever was. That’s why DSC didn’t do more of a radical change. I don’t think they needed to change it as much as they did, but it is what it is.
