Little blood is spilled, and when there is a death, everybody is truly appalled.
Many loud exclamations, but since the film is in Mandarin, how profane remains a question. Probably not a good idea. The subtitles will bother them, and everything is a little too complicated and, many parents might conclude, violent. They will love the fights and flights, and the rebellious young Jen speaks volumes to children. Assuming they aren't averse to subtitles, many teenagers will love this film.
