Parents need to know that Onward is Pixar's animated fantasy adventure about two elf brothers -- Ian (voiced by Tom Holland) and Barley (Chris Pratt) -- whose long-deceased father returns to life for a single day. But when only his bottom half appears, the brothers must go on a thrilling quest to complete the spell that brought him back. They experience peril and danger, go up against fire-breathing creatures, and find themselves in tense situations (like a car chase with angry pixies). The climactic fight scene involves large-scale destruction and sacrifice, but it's somewhat offset by the emotional nature of the brothers' desperation to have some time with their dad. The fact that the plot hinges on a dead father (and his half-body, when it returns) might disturb some young viewers, but ultimately it's more bittersweet than painfully sad. Language is pretty tame and mostly consists of insults ("weirdo") and words like "dang" and "what the ... " (cut off). Two adult characters are in a dating relationship, and another mentions her girlfriend. Families who watch the film are bound to appreciate its messages about teamwork, getting along with siblings, and acting selflessly and courageously.
