The movie focuses on 3 cops and a prostitute. I think it is clear that with this protagonists the movie has violence and sex as thematic element. But there is never anything strong or inapproriate for mature tweens. Some corpses are shown, sometimes bloody, sometimes decaying. The scenes are not disturbing. The character played by Russel Crowe is rude and a bit violent, but in contrast to him the character played by Guy Pearce is calm and gently. The role played by Kevin Spacey is neutral. The violence is never depicted in a way it could disturb or harm tweens. The movies has a prostitute as one of the protagonists, so there is sexual talk. No strong sexuality is depicted. The language is average R-profanity. If you don't mind the language, it is suitable for viewers 12 and up. And nowadays it would have been rated 15 in the UK and Ireland, not 18. Kim Basinger really deserved the Oscar she got for her role. Also Guy Pearce and Russel Crowe did an excellent job. Kevin Spacey is a very good actor, but this is not his best role, though not bad. Overall, a good and well made thriller.
