More brutal action than in earlier X-Men films.
Parents need to know that this comic book prequel isn't as tween-friendly as the earlier X-Men movies. Although many of the mutants are pretty indestructible, the action is still bloodier than in the previous films, thanks to the fact that much of it is carried out with the slashing edge of a claw, talon, or blade. There's also war violence, gunplay, a decapitated animal, and scary/grisly images of medical experiments, as well as kids being taken captive. Also expect mild male nudity (non-sexual shot of bare buttocks), and some drinking and swearing ("s--t" is as strong as it gets).
