Lemme say this about TAS, because I may have been too harsh on it in the podcast. I actually really liked the writing on TAS. Very creative, great stories, great TOS themes. I have nothing "against" it. The problem, though, is that there's really no way to rectify it with STC. We're trying to finish up the five-year mission through 2269-2270. Chekov is on board (unlike in TAS), Chapel is NOT on board (unlike in TAS -- she likely wouldn't have been on the ship in 2269-70 if she went to med school and became a doctor by TMP in 2272), there is no Arex or M'Ress, etc. So reconciling the two is difficult if not impossible.
Again, I like TAS; all I'm saying is that, for OUR purposes, we mainly have to ignore it.
