This movie was amazing, but it was also very depressing. I cried all the way through. I felt very sorry for everyone involved in the story.
The movie involves violence against children: definately the most upsetting part. All the women drink alcohol casually, and one is an alcoholic and abuses perscription drugs. There are a few mild sexual references but kids wouldn't get those anyway. I would definately say that most kids MY age would be upset by this movie, and maybe parents should wait until their kids are fifteen or sixteen to watch it with them.
Sandra Bullock did an amazing job, by the way.
