First, I have to say I'm 18 and I've read the books and loved them. The movie was SO close to the book that I was thoroughly impressed! I went to see it with my 14 yr old friend, 20 yr. old brother and 15 yr. old brother. My friend was in a little shock at some scary and violent parts. I loved the movie :)
Katniss and Peeta are great role models. Katniss because she took responsibility of her family (though she is a little disrespectful to her mom sometimes) and takes Prim's place. Doesn't want to kill but obviously, what would you do in a situation like that???
Peeta was good because he was constantly looking out for Katniss and didn't want to fight - though at one point it makes it seem like he does.
violence: blood splatters and you see gashes and blood smears. Rue is stabbed and Katniss has a knife cut her on her forehead. But most of the gore is offscreen.
Drinking: Haymitch - the mentor - is usually drunk and it shows him pouring his drinks and drinking from a flask often.
Language: there are a few "bad words" such as D*mn, H*ll, etc. Not exessive though. And at a couple of points you almost appreciate it cuz you would've said the same thing haha
Sex: Katniss sleeps with/on Peeta in the cave but they don't do anything. Might wanna discuss with kids that that's innappropriate, even though they didn't "do" the deed. They did kiss two or three times, and it was a little heated at one point but it wasn't long and drawn out to make you uncomfortable.
Scary: yes, it can be pretty intense at points. With Cato, the dogs, the girl with the knives - she almost kills Katniss - and plenty other parts. Not for the weak of heart -- or stomach haha
