Biggest theme is that families should work together, acknowledge each member's strengths and talents. Teamwork, communication, compassion, perseverance are promoted and exemplified. Other issues thoughtfully explored: self-identity, working mothers, at-home fathers, responsibility to help others, teen vulnerability, parent-child and sibling relationships. Marital dynamics also a theme. Another thought-provoking theme: people's complacency to what they see on screens and how easy it is to be manipulated by screens.
Many scenes of fairly intense, high-stakes violence, including threats to the city; superheroes cause some of their own destruction to rescue people. Frequent peril; children/parents in danger. Villain Screenslaver manipulates, controls others by hypnotizing them, either remotely or face to face. The supers must use their powers to attempt to save one another -- and regular citizens -- from Screenslaver-planned violence. Some weapons use, including a super-sized jackhammer. One intense/scary fight involves a lot of flashing lights, which could bother photosensitive people and has led to some seizure concerns. Baby Jack-Jack has hilarious but prolonged fight with a raccoon; Jack-Jack's powers include temporarily cloning himself, lighting himself on fire, shooting laser beams out of his eyes, spewing toxic reflux, and turning into a demon. A potentially upsetting story flashes back to how, in the middle of an armed robbery, a husband/father tried to call superheroes, but they didn't take the call, and the robbers shot him (viewers see the lead up but not the act itself).
A married couple kisses and hugs a couple of times. Teens flirt and have crushes. Elastigirl wears a skintight costume.
A use of "crap," "hell," and "damned," plus rude language like "boys are jerks," "superheroes suck," "superfreak," and "what the...." A couple uses of "oh my God."
Nothing in the film itself, but a lot of Incredibles merchandise off camera: apparel, toys, video games, figurines, accessories, etc.
Drinking, Drugs & Smoking
Characters make a toast/have cocktails at a gathering, and a wide shot of people at a restaurant who may or may not be drinking. Evelyn offers Elastigirl a cocktail (while having her own), and makes a joke about drinking on the job. Edna is shown briefly with her signature long-stemmed cigarette. Bottle of wine shown.
