We know that, if the CBS FX team had stuck slavishly to the original TOS designs, the argument would still be raging, only the topic would be about "missed opportunities" for the team to be brave, and to add some different stuff.
For me, there is sufficient freshness to make me watch every episode again, at least one more time - event the really bad ones. Love the baby horta in "The Devil in the Dark", Norman's innards, no strings on alien Korob and Sylvia, and yay the blinking Gorn (although I had liked previous fan explanations that the silver eyes, when compared to ENT's Gorn, were actually space goggles, so why would he have eyelids on the outside?).
There were definitely new fans of 24th century Trek - 21 seasons worth! - who were saying they had never seen TOS because it was too quaint. I have no problem with attempts to update the effects, and it was also good that they modernised them in a fairly random order, so the gradient of the learning curve isn't as obvious when the eps are viewed in original airdate or production order.
And yeah! Holodeck episodes. Where are they?
