Just a short comment to make some people aware that "predictability" is not per se a sign for a bad episode. Not all episodes of this series (or any series or any film, for that matter) aim to be unpredicatable and surprising. Not every film tries to be "Christopher Nolan". Some, for instance, aim to be psychologically sound - thereby telling a relatable and intense story. I found this episode to be very good since it creates relatable characters, takes its time to get into some (but not all, I give you that) nuances of the premise, creates a real dilemma that feels realistic for both main characters - and nevertheless takes it to an ending that shook me. Not as "gadgety" and superficial as some of the other episodes. I guess I'm just trying to say: The great thing about BLACK MIRROR is that certain episodes can be more psychological/"naturalistic" and others more "out there". Don't bash one episode for not being like the other.
Now one ship, 88 crew(the ones in the sickbay included), have vowed to drive back the night and rekindle the light of civilization. On the starship Discovery... hope lives again.
F. yes I'm gonna drop Andromeda quotes the entire season!
