This is a fabulous show that is incredibly well-made and well-acted! It is also absolutely not appropriate for kids. I have seen every episode and can say that most are disturbing or graphic. Many are also touching. The good guys are fully developed as people who care deeply about their country and risk their lives for it; they are also deeply flawed people. Characters the audience loves and cares about are killed off regularly. There are often very violent episodes and it is very realistic. The main scariness comes from the intensity and realism -- the safety of the public is in constant jeopardy, which can be very disturbing even to adults. Also, please note, that sex is a major issue. Though infrequent, some episodes DO feature full nudity (both male and female) and sexual activity. Most episodes of this program are not for kids.
