In terms of bad science going beyond the pale? "Spock's Brain." TNG "Genesis." VOY "Threshold."
ST Into Darkness. Star Trek is basically a 2 (IMHO sometimes rising to a 3) on TV Tropes' facetiously named "
Mohs Scale of SF Hardness," and that's a fine ballpark to play in, but problems arise when it drops down to a 1, and basically flaunts a brazenly anti-scientific sensibility.
Once again you seem preoccupied with sorting fans into camps and pitting them against one another. FWIW I think the problem with MU!Georgiou
in the first place was that she didn't add anything new or interesting to Trek, but rather detracted from it, in the vein of a mustache-twirling pulp-era villain... basically Ming the Merciless doubled down. I'm all for fleshing out characters, but it's better to start with one who was interesting in the first place, not a pure one-dimensional cliché. As
@Jadeb insightfully observed, That's what the writers wanted, and that's what they created... so if they want a different kind of character for S31, better to start with a fresh one. (Even Leland, for heaven's sake, seems deeper and more interesting by comparison.) I really don't see any signs of "depth" in her, at least not so far... and what's worse, given her origins, any signs she
may show are not to be trusted, as they can convincingly be interpreted as ploys to disarm or confuse others.
I would dispute that. Kor, Koloth, and Kang all showed signs of depth and interesting, distinctive personalities in their first appearances. (Lots of other TOS Klingons were just one-note villains, yes, but not those three.) If anything, they were much more disappointingly "stereotypical" Klingons (albeit in the Berman-era style) when brought back on DS9.
G'Kar at the start was
perceived by some other characters as a villain, but he was clearly much more than that... and yes, his development across five seasons was fascinating to watch. Of course, it was all written by J. Michael Straczynski, whose talent is head and shoulders above anyone working on DSC. (Which is why, IMHO, B5 was a better show than
any iteration of Star Trek.)
