The people who are complaining about the 11 year old girl cussing are missing the point.
The point is not about her cussing it is about parenting. Cage's character is a very bad parent who should be locked up.
He raised a little girl with no regards to her language, no regard for human life. Her turned her into nothing more than a really cute vicious attack dog with no more concept of morality than a doberman pinscher.
Don't get upset about her language, get upset and worried that kids today are becoming disturbingly too close to what she became.
