This is a great film for a great director and it stars one of the greatest actors of all time. I think that this film is like an 11+ the swearing is not a problem there is one F-Word...maybe 2, I saw it a year ago. But anyway, you hear worst language in a parking lot. The violence is infrequent but quite graphic, the climax shows a very realistic shooting victem (missing an eye, and covered in fresh blood) which is only made so much more disturbing by the character's child's tramatized (and maybe tramatizing) screams at their parent dead body, I don't belive in cencorship but I would say if you or you're child has lost a parent you might want to avoid the movie, the great perfomances make it all much more scary. The sexual themes are not a problem, a quick veiw of a breast and implied sex. The film may not be good for a few sensitive kids or teens but it such a good film, that any aspiring film maker should see it.
Even down to Roman Polanski's cameo as the "midget", the acting in this movie is great, Jack Nicholsen is great, especially because the role was just perfect for him. The film has smart dialogue, and a some-what hard to follow plot. The classic line "Forget it Jake, It's Chinatown" can fuel discussion in itself. This is most likely not a film that kids will be interested in, which is probably a good thing because there are plenty of scenes that make this a no-no for kids. And while it is probably appropriate for younger teens, it is best suited for older teens, because they will probably appreciate and understand it more then young teens.
