It's a good and evil story ... no surprises here. Friendship, love, bravery, and loyalty are always major themes in the series. So is the idea of making good choices.
Positive Role Models & Representations
Two deaths, including one very stirring death of a teen. No blood is shown, but lifeless bodies are. Children are in peril, often at the hands of magical creatures: dragons burn, chase, and cut Triwizard competitors; mermaids brandish spears as students are held captive underwater. A spider is tortured in a class demonstration. A hand is severed and sacrificed, and Harry is tortured by a curse, writhing in pain.
Some references to 14-year-olds' sexual interest; Harry is accosted in the bathtub by a ghostly girl; some couples kiss in the shadows after the Yule Ball.
"Bloody hell," "piss off," and similar words.
While the candy mentioned wasn't originally real, it is now: Bertie Bott's Every Flavor Beans, Chocolate Frogs, Jelly Slugs, and more. And then there are the action figures, Lego playsets, wands, Band Aids... you name it.
