There are a lot of issues in the movie--death, grieving, single parenthood, wayward teens, wayward dads, gangs and violence. I recommend that parents go see the movie, but not children. I know some kids watch violence on TV at home and their parents don't care. But for those of you who don't believe in exposing your children to things emotionally beyond their understanding and gun play, don't take your children under age 10. Or at least see it yourself first. Or wait and rent it so you can stop the movie during the gang stuff and talk about it.
You can watch a preview of it HERE. If this doesn't work for you, just go to youtube and type in Courageous preview.
