[Tyler tells Burnham about his plans for after the war]
Michael Burnham: Our futures look different. You go back to your lake house, and I go back to prison. My sentence was life. This is just temporary.
Ash Tyler: Well, maybe we just leave that transmitter alone. You can't go back to prison if we're still at war.
Michael Burnham: The needs of the many...
Ash Tyler: Are worth fighting for. Are worth dying for. But so are the needs of the few.
Michael Burnham: Or the one?

-I saw a review where a fan complains about the Stargate feeling of the episode and i want to say Stargate SG-1 especially has too great characters and is too optimistic and has too many sane stories to be compared with this wannabe Star Trek series. My rating reflects the quality of the series only as a sc-fi show,because it is the only one actual sci-fi show i can stand to watch.I really want to ask Roddenberry's son if he really saw an entire TNG or DS-9 episode with Klingons in his life ,before accepting to be a producer for this fake Star Trek ,where a dude wanted to mark his territory like a dog,changing the Klingons with this stupid version of bald lizards.I really hope some day a rich and real trekkie producer will make another ordinary Star Trek show without changing any TMP or TNG race at all just because he is a REAL fan,not a money lover.This episode looks just like Avatar,without the best part ,the first one,which is not a bad thing for a sci-fi production,but this series is (named) Star Trek ,although the Vulcans are the only one Star Trek species which appears in the show.This gay-sadomasochistic show becomes more and more hard to watch by a normal person.If you want something dark ,not something gay-sadomasochistic , you should watch Space Above And Beyond, because those producers know the real meaning of the word 'dark'. I'm so tired to see all kinds of ancient alien cultures with weird religions replacing modern alien races ,modern futuristic cities and modern cultures.
