‘Terra Firma, Part 1’: Sliding Doors
"Terra Firma, Part 1" works best if you think of it as the universe trying to teach its central character a lesson, like Groundhog Day did to Bill Murray. The mirror universe version of Philippa Georgiou, who has been a fish out of her universe’s water since she was brought over in the first season, has been walking around the corridors of Discovery for the past two seasons acting mostly like an insufferable jerk who is more caricature than character.
That caricature has at times been amusing (the one-liners are sometimes creative, and her aversion to all things Starfleet makes her an occasionally useful outside voice, when she’s not merely insulting everybody), but it has also become very repetitive and started to wear thin of late. But I’m suspecting now her unremitting abrasiveness this season was a deliberate ploy to set us up for this episode where she has to face the music.
