What parents need to know
Parents need to know that this is a review of the movie in theaters and not the Director's Cut that's available on DVD. This violent sci-fi action movie is bloody, gory, and grim. A man kills a wounded comrade in arms at point-blank range; skulls are penetrated by monsters' inhuman claws; extensive swordplay means limbs and heads are lopped off with remarkable frequency -- and so on. Plus, the film's overall tone is bleak, with a resigned cynicism that both evokes the old-school war films and makes the film a bit of chore to watch. You can also expect constant strong language, some crude sex talk, smoking, and drinking.
