Still don't get the complaint. Not everything needs 0to be a mirror to our times. Sometimes broader themes are at play.If I could summarize the message of the episode in a single sentence, it's "The system works." If you look at Star Trek as portraying a more optimistic future, that's completely fine as a message. But if you think of Star Trek as being an allegorical mirror held up to our present, it does come across as a bit icky.
She was hoping for something which was a bit more nuanced ala DS9, which didn't shy away from the dark underbelly of Starfleet. YMMV.
SNW has done dark before, no need for this one to be.
