Not just innuendos but themes that are more mature than we would associate with children. Not only for the parents accompanying their kids but good writing makes it possible to teach a young audience about otherwise difficult topics. Kung Fu Panda 2 deals with a whole genocide, for example. The Hunchback of Notre Dame had all that about religious fanatism and the deliberate racial persecution of a certain group of people. Thinking back on it, 101 Dalmatians had a woman chasing puppies to make a coat out of puppies. Innuendos are funny if you look back at them as an adult but that’s also what makes movies timeless and rewatchable even after aging out of the main target group.
