Apologies for not sifting through 68 pages yet, but...
There's a lot of terrific one-liners and moments that sweeten the pot, in an episode that's really good but (IMHO) is somehow the weakest so far in other ways. But it's still very strong.
Everyone gets something positive to do; Beverly and Jack get the best bits.
Jack's namesake scene (re: Beverly's hubby) was good.
Good continuity: a changeling does need a pot or something to ooze in while regenerating. Was the drug joke really needed, though? This isn't "The Orville" or any of the 90s TNG flicks, and - overall - season 3 feels like a cinematic experience that the 90s ones should have been.
Shaw's background reveal of being at Wolf 359 stings and the universe is a large enough place.... Shaw is still a terrific breakout character with his own path (a big plus), and yet I still can't help comparing to Sisko (whom I like more). The Shaw being a grease monkey from Chicago story still works, and the one-liner about how "
They even gave you a name" regarding the Borg is still very chilling. But even admiral Hanson in TBOBW said Picard was a casualty of war. His body was used literally as a puppet and would not Hanson tell the fleet that? Picard did and could do nothing, which is a level of chilling that nothing since could top, but this does come close...
A captain should know the high-level functions of every system, but Riker also gets to be chief engineer for a moment.
The Changeling appearing as NotLaForge was a great moment.
Picard says the F-bomb. A bit of a surprise despite it all, but it didn't feel needed or really in place. More impressively, he also channels Data when reciting Shaw being a (bleep) from Chicago.
Riker gets a memorable line at the end about not being able to hide from the pain by being alone.
The holodeck and its separate power source (really?) couldn't be shut down just so its power could prevent that "we have 0% anywhere, even life support, see the lights go down but we're not floating" scene? Contrivances aside, there is a rather positive thematic reason for the scene (esp. the callback with... Jack!!!... in one scene, as well as background setting building.)
The space jellyfish... It's a weird touch. Not bad, but not sure what to make of it. Very surreal. TOS and TNG both have histories with spacefaring lifeforms, the latter with "Encounter at Farpoint", "Galaxy Child", "Tin Man", "Silicon Avatar", et al. It's definitely a new take on the trope, and by the 21st century, it's weird that Trek would continue it... but it's a new twist. Can't hate it, but it's as weird as it is oddly satisfying.
Riker playing "fling it" by chucking an asteroid onto Vadic like how she whipped the Helios at them was still slick.
The scene that starts by inspiration from "Booby Trap" gives a great command moment for Picard, while letting LaForge continue to be helm.
At this point, at little more info on Vadic and the Changelings would be nice to up the ante, though with six episodes left, more would be coming - why the performance art with her hand when it attaches back on with ease, after removing it just so floatydemonthingy can talk and threaten her? Otherwise, if it weren't for Amanda Plummer, the character wouldn't be memorable as there's not much on the script. And yet she steals the scenes she's in. Huge kudos to her acting for making Vadic memorable and more than what's on paper.
7.5/10, will round up.
