I'm going to have to quibble with that a bit. Even on TMP Trumbull said he'd have preferred a much larger model in order to make the ship look appropriately huge.
But Trumbull was coming from 2001 and Silent Running.
The TMP Enterprise was larger than the Phase II Enterprise (8 feet compared to just over 5 feet for the Phase II model). But ILM hated the TMP Enterprise for it's size, which is why the Reliant model was about two-thirds the scale of the refit model (and both models got the same up close types of shots in TWoK).
But you are right... for somethings you need something more than the hero models, and both the refit and Reliant had "bigiatures" stand-in sections made for them.
Exactly... which is why I consider my daily trip to the airport totally unrealistic. After all, each day I'm faced with seeing airplanes that look essentially unchanged since 1965.
In films, as in all fiction, the lamest excuse for the implausible is "it happens in real life." The only measure of plausibility is what an audience will accept, and there's no reason to think that what the few traditionalists want in this case would have impressed anyone else.
Funny... audiences have proven that they are capable of accepting a great spectrum of things. But of course I wasn't advocating one over the other, just addressing this quote...
"Well technology moves on you know...as credible as the design was in the 60s, its just not for today."
You could address that quote as well.
Just a thought.
