You're the hero of your own story. The people we love are never completely gone, because they live in our memories and our stories about them. Your story will live on even after you're gone. Courage, teamwork, and empathy are strong themes.
From the opening scene, there's peril and violence in the story. Characters are injured and die. Kubo's eye was stolen by his grandfather, and his father was killed. The fights between the Sisters and Mother and later the Sisters and Monkey, Beetle, and Kubo are intense. Beetle is unexpectedly stabbed in the back after a battle is seemingly over. The huge, scary skeleton almost eats Kubo and his friends, and Kubo almost drowns in another sequence because of hypnotizing sea creatures. The Moon King turns into a frightening giant serpent. An entire village is burned down, but most of the villagers survive the fire. Kubo and his mom wash away upon a shore to hide, and his mom hits herself on the head. The scene in which Kubo is spotted is spooky; his masked aunts say his name in a really eerie way.
Kubo's mom recalls how she and his father met and fell in love. In between bickering, Monkey and Beetle flirt a bit, and she gives him a soothing massage.
Occasional insults like "stupid," "idiot," "an embarrassment," and "weak." Swear stand-ins like "ohhh foot!"
Nothing in the film itself, but plenty of real-life merchandise/promotional tie-ins.
