Parents need to know that "Spider-Man: Into the Spider-Verse" is a funny, original, action-packed animated Marvel adventure that centers on Brooklyn teen Miles Morales (voiced by Shameik Moore), who becomes a new Spider-Man and ends up meeting other Spider-people from parallel universes. It's sure to appeal to Spidey fans of all ages, and it's more tween friendly than the live-action wall-crawler movies, but it's still pretty intense. And while the violence is mostly cartoonish, there are lots of fights that involve weapons (including guns), injuries, and even death. (Spoiler alert: One version of Spider-Man dies, as does an important supporting character.) There's also large-scale destruction, as well as frequent peril, suspense, and mortal danger. Characters flirt a little and occasionally use words like "hell," "dang," "fat," "stupid," and "dumb." But kids won't fail to notice the movie's diverse characters and clear messages about friendship, courage, mentoring, perseverance, teamwork, and (of course!) the nature of power and responsibility. Jake Johnson, Hailee Steinfeld, and Nicolas Cage co-star.
