This was one of the best films I've seen in a long time. I don't even know why I liked it so much, I just did.
Violence is pretty strong, but the camera quickly cuts away. There is a pretty brutal blood bath, with images of blood splattering and showing clips of the dead. Mutated wasps attack a girl, and she is shown and looks pretty disturbing. A lovable character dies which greatly affects Katniss. Characters are shot, speared, and crushed to death.
Language wasn't an issue at all, I'm pretty sure the worst it gets is 'damn'
A couple kisses, nothing much.
This movie does have pretty good messages, the main one revolving around rebelling against something that's wrong.
It may be violent, but it has a point. Leave the young home.
