Common Sense Note

Parents need to know that this sometimes-creepy sci-fi drama includes explicit violence, and the entire concept -- aliens are taking over human bodies -- can be somewhat unnerving. Once they've been changed by the invaders, some characters have uncontrollable murderous urges and no sense of right and wrong.

Sexual Content

Some making out, and plenty of skimpy outfits. No explicit sexual content, but some episodes make it clear what the characters are doing off-camera.

Violence

Fairly frequent realistic violence (including several murders), but the graphic nature of some scenes demonstrates that real violence has painful consequences. Also, some scenes show alien creatures attacking people abruptly. The violence has increased as the season has progressed.

Language

Mild ("damn," "hell," "ass," etc.). Some of the characters have occasional heated arguments.

Social Behavior

Authority figures are in clear, constant conflict. The local sheriff takes advantage of his position to manipulate townspeople and facilitate an alien infiltration. Among the people who have "changed," wildly antisocial behavior (murder, theft, deceit) is common.

Consumerism

Not applicable

Drugs / Tobacco / Alcohol

Several adult characters drink beer, though not to excess, and some episodes include scenes featuring teenagers drinking at parties.
