Parents need to know that Shang-Chi and the Legend of the Ten Rings is the action-packed origin story of Marvel Cinematic Universe superhero Shang-Chi (Simu Liu). The son of The Mandarin (Tony Leung) -- the superhumanly powerful leader of the underground criminal organization the Ten Rings -- Shang-Chi was trained as an assassin from an early age. As a teen, he abandoned his destiny in order to live a normal life, but his father sends muscle to force him back home a decade later. As in all of the MCU movies, families can expect lots of sometimes-intense comic book-style violence. Most of it is martial arts-based and involves heavy hand-to-hand combat, although characters also occasionally use guns, bows, spears, and other weapons (and, naturally, things blow up). There's a fairly large body count, frightening demon-like creatures, and a couple of deaths that may hit viewers hard. Language is infrequent but includes "s--t" and "damn." There's less romance in this movie than in other MCU entries, with the exception of flashbacks to how two characters met and fell in love (there are a couple of embraces and kisses). The film is notable for featuring a nearly all-Asian cast (including popular comedic actor Awkwafina as Shang-Chi's best friend), as well as for its messages of teamwork, perseverance, and courage.
