Survival is a religion.
Why it is hard sci-fi
A two-season series in which two androids, Mother and Father, are programmed to raise human children on a recently-evacuated alien world after Earths religious civil war. The show commits to a working set of hard ideas. The colony ship architecture, an atheist pedagogical program, a working necromancer-class android with a built-in mass-destruction capability, and a recurring engagement with the religious politics of the human refugees who arrive later.
Science inside it
Android pedagogy as an engineered childcare program, a planetary biology that the show progressively reveals as an engineered cycle, a necromancer-class weapons platform with a screaming-frequency kinetic capability, and a working set of religious-political models in which faith is treated as a real social-engineering force. The shows worldbuilding is rigorous about the fact that the colony is a deliberate experiment.
