Common Sense Note
Parents need to know that this is a very grown up movie depicting extremely complex father-son dynamics, exploring the good, the bad, and the ugly of their relationship. That means infidelity and, at times, emotional cruelty. Some scenes depict the son as a teen, complete with raging hormones. Though there aren't any explicit nude scenes, his growing fascination with the opposite sex is explored (there's a masturbation scene). He also drowns his sorrows in hard liquor at one point, and there's some swearing. If your son is going through a rough patch with his father, see the movie ahead of time so you can unpack some of the complicated emotions the movie is guaranteed to raise.
Sexual
Content
No explicit nude scenes, though couples in varying/implied states of undress are shown about to make love or making love (for example, a teenage couple is shown under the covers with bare shoulders). A teen boy is briefly shown masturbating under the covers. In front of his son, a father cozies up to a woman who isn't his wife. Some kissing and discussion of the "sex police."
Violence
Raised voices in argument, but no physical fights.
Language
Some salty language, but not on overload. "S--t" is uttered in the first few minutes, and in one scene with strong emotions, a character screams "f--king" several times. Other language includes "bloody," "hell," and "damnation."
Social
Behavior
A father who is otherwise attentive seems oblivious to his son's feelings, insisting on getting his own way, making fun of his son (he calls him a "fathead"), and conducting an affair in front of him and then asking him to keep mum, even though the son is still a kid Another character kisses a woman who isn't his wife. Nevertheless, most of the characters are well-intentioned and are searching for the right answers.

Book covers are clearly visible (one character reads a lot); some brief product mentions, but nothing obvious.
Drugs / Tobacco /
Alcohol
Visible consumption of alcohol -- mostly in social situations, though a teenager is shown drowning his discomfort in hard liquor that his own father buys for him.
