For those kids and parents who've only watched a little bit and say there isn't any sexual content other than some things the boys say, IT DOES HAVE SOME VERY EXPLICIT SEX. Bad enough that I, a 16 year old, would skip scenes because of it. While I don't know exactly where it starts, Dean, and later Sam, are in some very inappropriate situations. I would definitely NOT LET A CHILD UNDER THE AGE OF 15 WATCH (and only at 15 if you KNOW YOUR CHILD VERY WELL and they understand what is ok and what is not, especially if you're Christian, as the show revolves around the existence of demons and only in the fourth season does the existence of God ever really come to light - though we find out earlier that Sam believes in God already while Dean is a pretty adamant atheist. In this, questions such as "how can a loving God let all this happen" come up, so you may want to talk to your child about this beforehand). As for violence, it's pretty much the basis of the show. Some creatures are really scary, and while I'm not squeamish some of the images and violent parts are really disturbing. Ex) At one point someone gets their heart ripped from their chest while they're still alive (it's very painstaking and he's completely conscious the entire time), and at many points people get their head sawed/ripped/sliced off, a lot of gruesome deaths, decaying corpses, decayed skeletons, horrible crimes humans commit (rape, murder, hiding bodies)... so in all know your child very well. If you still want to let them watch the show (and it's an amazing show to be sure), it might be better if you WATCH IT WITH THEM (with a black towel handy) or WATCH IT BEFORE THEM (in episodes would probably be easier, as there are 10 seasons and by the time you'd finish they'd probably be young adults anyway). As for language, it's nothing more than you might hear walking down the hallway in high school (though in saying this I'm admitting that it can be pretty bad, although I'm pretty sure they've never dropped an F-bomb). As role models, Sam is a pretty good one (in the beginning, at least), not wanting to kill innocents if possible, and not as sexually casual as Dean, though the first episode shows him living with a girl in college. Dean is less of a good role model, but if you can get past him being an explicit player and violent monster hunter, you can see that he has a lot of problems and has a hard time talking to Sam about his feelings. As for drugs and alcohol, THEY DRINK QUITE A BIT (casually, usually, though sometimes they might actually get drunk for certain reasons). The only drug reference I can think of is when they use it as a cover for having to fight a possessed bus driver. Also, the boys usually do some other illegal things, such as using many fake identities and badges and credit cards. They pickpocket and break into houses and burn corpses in cemeteries (to destroy vengeful spirits). So be careful with this show, and know your kid. Otherwise it's a very action packed show with thrilling horror and an awesome (though very dark) plot.
