XO, Kitty: parents' guide
Best for ages 13 and up. Rated TV-14.
A bubbly teen romance from the To All the Boys world, set at an international school in Seoul, that suits young teens watching with a parent. Kitty, whose mother died years earlier, goes looking for her mom's past and finds a tangle of crushes instead. Across three seasons, expect lots of kissing and making out between straight and same-sex couples, talk about sexual dreams and birth control, underage drinking with some drunk teens, and swearing that tops out at the s-word. Violence is minimal. The romance-heavy plots and party drinking are why it sits at 13 rather than younger.
What's in it
Violence
MildVery little: arguments, a boy shoving another into lockers, and Kitty being struck by a car in the first episode without real injury. Nothing bloody or graphic.
Language
ModerateSwearing is occasional and tops out at the s-word, alongside damn, ass, bitch, hell and frequent use of God's name, including goddamn. Neither source reported an f-word.
Sex and nudity
MildRomance drives the show: frequent kissing and making out, a couple kissing in a hot tub, talk of sexual dreams and contraception, and flirty comments. Season 3 adds suggestive party talk and an adult pregnancy subplot. Same-sex romances are central. No sex scenes or nudity.
Drinking, drugs and smoking
ModerateTeens drink at parties and some get drunk; in season 3 an underage girl slurs her words and tipsy partygoers pressure someone into taking shots. Adults drink champagne and liquor. No drug use was reported.
Scary or intense scenes
MildMostly light. Kitty's grief and curiosity about her late mother give some episodes an emotional pull, and there is a brief car scare, but nothing scary or intense.
Sensitive topics
- Death of a parent
Worth talking about
Kitty moves across the world chasing a boyfriend and her mother's story. What does she learn about the gap between the people she imagined and the people she finds?
