Slow-moving Battlestar spin-off best for big fans.
Parents need to know that this spin-off series will appeal mostly to fans of its parent show, Battlestar Galactica. The storyline traces the origin of the Cylons, robotic villains that nearly annihilated the human race. There’s some drinking and smoking by central characters, and a few scenes feature sexual themes that make the show most age-appropriate for teens and up ... but the bigger issue is that the complex plot might not appeal to viewers who aren't steeped in Battlestar Galactica lore.
