13 Reasons Why: parents' guide

Graphic and upsetting. Several rapes of students are shown, including a brutal assault on a boy with a mop handle. Also fights, a fatal car crash, a student's gunshot suicide attempt, a planned school shooting with stockpiled guns, and a season 3 killing.

Frequent strong profanity throughout; one count of the first episode alone found about 4 f-words and 10 s-words, plus "dick," "ass" and misuse of God's name. Also sexual slurs and cruel name-calling aimed at girls.

Teens make out, masturbate and have sex, including one fairly explicit scene, though without nudity. A boy shares an upskirt photo, sexual rumors drive much of the plot, and later seasons include an abortion and a homeless character doing sex work.

Teens drink heavily at parties and use cocaine and ecstasy, and steroids drive a season 3 plot. One main character becomes addicted to heroin and is shown high and in withdrawal, and his mother dies of an overdose in the final season.

Bleak and emotionally intense: Hannah's suicide and her parents' devastation, a second student's suicide attempt, panic attacks, hallucinations and PTSD, and a final-season death from AIDS-related illness. Netflix added warnings to the most graphic episodes.
