And, honestly, there's no point in doing a new Trek show if you're not going to at least try to put a new spin on it. Now, how far you can tamper with the recipe before you lose more than you gain is always going to be a judgment call, which people of good will can debate, but, again, that doesn't mean you "hate" or "have never watched" the previous versions; it can just mean "we've already done X, so let's trying doing Y this time around."
To be fair, I can certainly empathize with a feeling of “I loved X and miss it so much, I just want more of it, done in the same manner please!”
(I’d very happily watch “new” episodes of TOS [or especially, a post-TMP TOS], or any number of other shows from my youth, if they could magically be created; and I’m very much looking forward to the new Muppet Show special. Same way I really, really wish I could get more Roger Zelazny Amber novels.).
But it would be economically unrealistic, culturally unlikely, and in most cases probably creatively stagnant to do so.
