Alright, let's do this:
- ✘ Star Trek S3E1 “Spock’s Brain” — Hilarious, doesn't belong in the list.
- ✓ Star Trek: The Next Generation S1E4 “Code of Honor” — Offensive, belongs in the list.
- ✓ Star Trek: The Next Generation S2E22 “Shades of Grey” — Clipshow, belongs in the list.
- ✓ Star Trek: The Next Generation S2E18 “Up the Long Ladder” — Offensive, belongs in the list.
- ✘ Star Trek V: The Final Frontier — Shatner did nothing wrong, doesn't belong in the list.
- ✓ Star Trek: Enterprise S4E22 “These Are the Voyages…” — Never loved Enterprise, but it didn't deserve to have its finale hijacked. Belongs in the list.
- ✓ Star Trek: Section 31 — Terrible, belongs in the list.
- ✘ Star Trek: Strange New Worlds S2E9 “Subspace Rhapsody” — Wonderful, doesn't belong in the list.
- ✘ Star Trek: Discovery S1E1 “The Vulcan Hello” — Love Disco, doesn't belong.
- ✘ Star Trek: Lower Decks S1E1 “Second Contact” — Lower Decks started slow, but was never bad enough to belong in the list.
- ✓ Star Trek: Scouts S1E4 “Asteroid Blasters, Number 4” — Never continued past the first episode, but I expect this belongs in the list.
- ✓ Star Trek: Voyager S2E9 “Tattoo” — Offensive, belongs in the list.
I'll go to bat for it. The existing Klingon makeup was initially pretty fearsome, but had become too friendly and familiar to the fans. We'd watched Worf get beat up 100 times, get married, and fret over a pimple, and we'd seen too many jolly Klingon blood wine parties. It wouldn't have been effective for Discovery's story of a truly alien warrior race re-emerging after 100 years and going straight for Starfleet's jugular. A dramatic redesign was the best most effective way to put us in the characters' headspace for the Klingon war arc. And they'd already been reworked in the past, so why not again?
(I appreciate that you oppose each redesign, though! Rarely see that consistency.)
