It was okay, but no great shakes for me.

Aside from the B&W gimmick, this was probably the least SF Trek has been for a while - it’s basically someone wanting to do a WW2 Nazi/Resistance movie and selling it with the film noir scheme. I wish it had leaned more into the noir idea of having doubles.

I did wonder about the obvious plot holes: why the D7 never detected the shuttle, how they managed to get an ID card for Uhura despite her making up her alias apparently on the spot, or how the EMP didn’t fry the shuttle’s systems, too. Also, why Kor’s makeup reminded me of Tuvix, and why he didn’t press harder knowing she was lying about not knowing about colour or not recognising the Starfleet symbol. He had pretty much all he needed to know. Some of these you can handwave away, some of these you can squint it through, some ask for at least some explanation.

I’ve never liked the idea of Hodgkin’s Law of Parallel Planetary Development, and I like the doppelgänger equivalent less. The coincidence of Una looking like Nevette is bad enough, but that Nevette happens to be the head of the resistance and the collaborators and a double agent best placed to move the plot along? Too much for the “you should get the audience to only buy into one implausible thing” plot rule.
