Seska and Ebert agree, "Worst Case Scenario" wins!
I'm surprised "Scorpion" lost, as it's (IMHO) the best Borg story since TBOBW, which is surprising...
Flashback - a retconning of ST6 TUC was a weird way to celebrate the era... complete with footage reused with a orange creamsicle color cast instead of the original purple/pink. If nothing else, 1:13 shows the difference between SD and HD far better than faffy upscaling could try to mimic:
It was probably easy to remember the lines, but the episode felt like everyone was phoning it in.
That said, this
was Tuvok's recollection, which is a neat in-universe way to explain every bit of minutiae so it's silly to be too harsh...
...then again:
Yup! The 30th anniversary special smacks the original series rather than celebrating the franchise. Albeit unintentionally; Janeway's trying to make some parallels with her crew's plight, combined with comparing technologies -- it should come off better than it does. "Sulu, Kirk, McCoy, different breed of officer..." and all because they do what Picard and Sisko and Janeway too I'd imagine have done and not bored the XO's to sleep with overly-wordy details that only Tuvok, Spock and I would appreciate.
False Profits - naturally, the other side of the wormhole from the classic episode 'The Price' ends up being in the Delta quadrant. It's also a bog-standard runaround that smacks of TNG season 7 vibes. It'd be more fun if the wormhole ended up in that corner of the Alpha quadrant that everyone forgot about and how Geordi's sensors were wrong...
The Q and the Grey - starts out as a sophomoric running gag but goes south once they do the allegory of the 1860s American civil war. Also, no pun was intended. Also note, it can be sophomoric and still funny. Humor is more subjective than anything else...
Also: Aww man, it's "The Orville" a couple decades early!

Ditto!
Macrocosm - it may be Trek's latest take on "Aliens", but the high concept premise of a virus being increased in size exponentially is put to decent and novel use.
