i'm guessing if the branch of the franchise that's supposed to be a direct prequel to TOS isn't doing this, neither is the big budget, flashy, far more disconnected film series.Maybe even take a page from TOS and go with a "less is more" approach: simpler, clean cut lines and bolder aesthetics.
i'd prefer they embrace the bright, shiny futurism even more. not saying they should double down on the apple store look, everyone's done that in the last 9 years, but they should try to find new ways to make the enterprise and starfleet et al feel exciting and advanced and optimistic.
but you're right, no grime. i appreciated that they added subtle wear to the enterprise in beyond, but that was part of that film's narrative, despite the enterprise being less than 5 years old.
