In addition to vivid world-building and unique rule-setting, one of the things I always appreciate in a good science fiction show is how the themes reflect modern-day society. Whether a militaristic space opera set on a distant planet or a grounded, near-future story set on Earth, the most lasting sci-fi shows use allegory to make a profound statement on the state of the world. Star Trek famously addressed civil rights in several episodes, while newer shows likeSilo use futuristic pollution to justify oppressive totalitarianism.
