One f-word joins about a dozen minor profanities, including s--t and d--m. The violence is pretty shocking for a superhero movie—20th Century Fox seems to be making a stand against Marvel's Disney offerings by upping the on-screen body count significantly. People are ripped in half by Sentinels (though are transmuted when they do so, so no gore appears), stabbed, burned, frozen, decapitated—Sentinels really are extraordinarily violent machines. Various heroes assault guards and various nemeses, hitting them with objects or slashing them with claws. One character is shot in the leg and then dragged across the ground by a character controlling the metal in her leg. Another character is hit with a cinder-block, and then has rebar metal twined through his body to paralyze him—the camera watches it all. (Even as an experienced movie-goer, this last scene made me squirm.) Definitely leave the >12s at home for this one.
One character goes clothes-less much of the movie, but has scales that obscure her anatomy up to the level of let's say Generously European standards. Another has her bare back shown, and we see her in a bra.
