“Children of the Comet” is a rare Star Trek tale where music saves the day. In “Children of the Comet,” the latest episode of Star Trek: Strange New Worlds, music plays a key role in resolving a crisis. La’an, Spock, Sam Kirk, and Cadet Nyota Uhura—on her first away mission—are trapped under the force field the “comet” M’hanit generates. Sam commits the rookie mistake of getting himself zapped when he gets too close to the large “egg” on M’hanit’s surface. (Did Sam never watch Alien? Maybe the movie didn’t survive Earth’s Third World War.)
