Here’s the thing that people keep forgetting about TMP, when they use it as some kind of example about what CBS is doing now with their shows: The visual changes shown in TMP was Roddenberry’s way of invalidating TOS, not adding to it. His vision at the time was not that ‘this was always how things looked,’ despite fandom interpreting it that way. His vision was ‘TOS as shown, both visually, storywise, characterizations, continuity, etc. etc. didn’t really happen the way you saw it. As a matter of fact, if you want to ignore it entirely, please do so.’
