I'm sorry but why do you see that as a problem? The world has changed, why stick ridgedly in the past? I respect you have different opinions but with the TMP thing they are expected to make it fit.
Because if it were meant to feel so authentic they wouldn't be so obvious about what they're doing.
There a lot of things I like about STC, but I can't ignore the things that keep it from feeling like a truly credible extension of TOS.
This started way back in "Pilgrim Of Eternity." I could let the proto holodeck go because the idea had been conceived during TOS and actually done in TAS. But creating the character of McKennah as ship's counselor was a no-no. That wouldn't have happened. And I like McKennah as a character and I really like the actress.
Still, I could let that slide some even though her presence affected the familiar character dynamics. Lines went to her that originally would have gone to Spock or McCoy. I will say they have used her sparingly and to no real detrimental effect story wise. And it helps she is a good actress.
"Pilgrim Of Eternity" was a good showcase of what STC could do and what they were aiming for. But the biggest issue was doing a following up story to a story that didn't need one and to indulge in something that TOS almost never did. Indeed they only did it twice: following up "The Cage" with the two-part "The Menagerie" (and it wasn't meant as a followup) and followup up "Mudd's Women" with "I, Mudd."
There were other quibbles regarding writing Kirk more like Picard and using contemporary style technobabble, but overall it was a good and respectable start.
But Ep. 1 would prove to be more of a template for what was to come than was initially believed. Easily half of STC's episodes have been followups. Polished execution notwithstanding TOS simply wouldn't have done that. And they certainly wouldn't have made a practice of referencing things that did not yet exist or foreshadowing events of which they had no knowledge whatsoever.
This is the stuff of conventional fanfic and novels published by Pocket Books. It's pure continuity porn.
It's not what the writers back in the day would have done. I can get behind slipping in a few new things that could have been done given the chance and resources. But any tangible sense of authenticity is blown when you keep dipping into a well that simply wouldn't have existed back in the day or indulge in practices the original creators wouldn't have done.
But, hey, doing followups is unquestionably easier than coming up with wholly original stories. No argument--that ain't easy.
