Parents need to know that this movie has intense gore, which falls just on this side of a slasher film. All kinds of decapitations, bloodletting, tracheotomies, etc., are inflicted on various human-like beings. Although the vampires combust in a cloud of sparks when killed, it comes too late to avoid seeing brains, hearts and tendons, and oceans of blood. Blade, at one point, gets strapped to an impalement table, which shoots spikes through various limbs and organs. There is also a scene of horrible vampire self-mutilation. Even by action-movie standards, it is very graphic. Characters use strong language and there are sexual situations. Interestingly, in the original Blade, the vampires were a rainbow nation of evil with many different ethnic groups represented, but in Blade II, there are two ethnic vampires on Blade's hit-squad, but none in the crowd scenes, or as antagonists.

Families can talk about the movie's themes of betrayal and loyalty. For what it's worth, Blade is a black superhero. He calls the shots, is never condescended to, and shows loyalty, courage and integrity. Parents may want to discuss the nature of wish-fulfillment, and the way violence and problem-solving are conflated in the movies versus the way they interact in real life.
