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.
Very little -- some flirting, tame kissing, implied non-sexual nudity.
Moderate -- some gunfire, a little blood, fistfights, explosions, an attempted suicide.
Most central characters are positive role models, but some other characters lie, manipulate, and engage in violence. The cast is moderately diverse, with both men and women in central roles.
Drugs / Tobacco /
Some social drinking. Medicinal drugs are a central theme, with hypodermic needles often seen.
