I don't see the contradiction here.
Of course you don't.
Theme music is another example of this, illustrative of the point. ... Now, I don't need theme music to be consistent across all series.
Of course not, because
theme music is a non-diegetic element. It's literally the standard example of what it means for something to be non-diegetic.
You surely understand this, yet you've blurred this distinction again and again throughout this thread, and I honestly cannot fathom why.
Theme music can't be detected by the characters on screen. Neither can the status of makeup
qua makeup (that is, as something other than the actual look of a character), or props
qua props (e.g., transparencies in place of bridge monitors), or the different appearance of a stuntman/woman. These things cannot be noticed or observed by anyone within the story.
Sometimes the distinction is subtle. When the
Discovery spins like a top on its horizontal axis upon activating the spore drive, this effect is (presumably) non-diegetic. On the other hand, when characters within the ship see things like drops of water floating as the drive activates, that is diegetic. Like the theme music, the spinning is a non-diegetic element meant to enhance the experience; others, like detectable makeup, are simply unavoidable and need to be ignored to avoid detracting from it.
The actual physical appearance of ships and uniforms and weapons and sets and the like, in
Star Trek and almost every other film and TV show ever put to screen, is understood to be diegetic. Characters interact with them. They're part of their reality. Unlike with stageplays and their very severe physical constraints, the stuff we have to make allowances for is relatively minimal. Visual elements like these are meant to be as close to verisimilitude as possible,
not something to ignore.
Consistency of diegetic elements is important for maintaining the willing suspension of disbelief that's essential for immersion in a fictional reality. So when you say that consistency between different productions doesn't matter, even though those productions purportedly share the same setting, you should hardly be surprised when viewers react to the assertion that the setting
is the same with... disbelief. It makes perfectly reasonable sense that the effort at consistency should have the same scope as the fictional reality in question, whether that's limited to a single production or continues across many.
I don't need phasers to always sound the same...
Well then you're confused, because a sound effect (unlike theme music)
is diegetic, i.e., it represents the actual sounds of things within the story. As such, phasers
should sound consistent (at least, when they're they same kind of phasers within the same period setting).
...The only thing I require of the VFX is that they not look cheap and/or tacky.
And again you're confused, because the amount of money invested in the FX has fuck-all to do with whether the thing being depicted is diegetic or not. (And whether they look "tacky" is, of course, irreducibly subjective... just as much as whether they're "impressive" or "exciting.")
"Technical proficiency" and "trendy and flashy and eye popping" are mutually exclusive.
Then by all rights you really ought to despise the FX on DSC. For instance, they seem utterly incapable of depicting an outer space vista that's not chock-full of glowing nebulae and harsh blue light and long-zoom shots into ship windows.
Do you really expect me to go down the rabbit hole explaining to you what that term actually means and why it is not meant to be a dismissive term, or would you prefer to address what I actually wrote?
What you actually wrote was "Any version of the 23rd century Starfleet that didn't involve frankenbashing TOS-constitution parts together in various configurations was going to drive legacy fans completely bananas no matter what they looked like." If you don't see how that's dismissive, then
you're the one who's not paying attention to what you write.
