Parents need to know that this intense crime/trauma drama is meant for adults. Detailed scenes of death (a cop chokes on his own blood while trying to communicate his last words for his family) and bloody violence (a surprise flurry of gunshots instantly kills one person, whose blood is splattered across a car window) are standard fare. Language is particularly strong for what was originally a network show -- expect to hear "bitch," "ass," and sometimes even more; repeats run on cable, which has looser standards. Mature themes regarding relationships -- friendly, hostile, and intimate -- permeate the show.
Positive messages:The primary characters are mostly "good guys," though they're all humanly flawed. Characters struggle with attitudes, anger, divorce, infidelity, and more.
Violence:Frequent bloody, detailed violence -- often related to traumas -- including gunshots, death scenes, tense chases with guns, and physical violence (such as one scene in which a police officer kicks a suspect in the face). Deals directly with the impact and aftereffects of the 9/11 terrorist attacks.
Sex:Romance, intimacy, flirting, some sexual joking and passionate clinches.
Language:Lots of profanity for a show that originally aired on broadcast television. "Bitch," "ass," etc. are frequent, and stronger offenders ("f--k, "s--t") aren't always bleeped/muted in cable repeats.
