Common Sense Note

Parents need to know that this sci-fi drama series centers around the idea of being abducted and then returned to earth many years later. Younger viewers, if they're not bored by the adult-oriented material, may need reassurance that the concept is fictional. Some violence occurs, like when a criminal is wounded by gunshot or a fistfight results in near death. In one episode, a main character attempts suicide, though she's quickly revived. Several characters have special powers, some of which are creepy or scary -- like the pulsing gills on one character's torso.

Sexual Content

Very little -- some flirting, tame kissing, implied non-sexual nudity.
