YMMV / Hellboy Animated

• Complete Monster: Erzsebet Ondrushko from Blood and Iron is an evil countess based on the infamous Elizabeth Báthory. Consumed by her vanity and wishing to stay young and beautiful forever, Ondrushko sold her soul to Hecate, the Greek Goddess of Witches. In return, Hecate transformed Ondrushko into a vampire and gave her the power to rejuvenate her body if she bathes in the blood of young women; she is said to have murdered over a thousand people in her quest to remain young. Through a series of flashbacks, we see Ondrushko take over a dress shop, by murdering the shop owner and her infant child, to lure in and kidnap a young girl named Anna. Anna's fiancé gathers a rescue party, including a young Professor Broom, which goes to Ondrushko's castle, which is filled with torture devices and the bodies of young women. Finding Anna drained of blood, they kill her to prevent her from becoming a vampire as well. Ondrushko kills most of the rescue party, but Bloom manages to kill her. Though her body died, her evil spirit remained. Sixty years later, the BPRD is sent to investigate a supposed haunted mansion, which is in fact haunted by the souls of Ondrushko's many victims. Ondrushko's minions resurrect her and she bathes in the blood in the mansion's owner to rejuvenate herself.
• Values Dissonance: Many Western viewers don't understand why the Samurai's actions in Sword of Storms shamed his Daimyo. A brave hero who rescues a fair maiden from evil demons and spares his liege lord the horrible choice between sacrifice and destruction is the foundation of European Legends and Fairy Tales. Such deeds usually earns the hero a reward—the maid's hand in marriage or a lordship of his own, not being turned into a statue and his love murdered by her own father. Long story short, the samurai was the daimyo's servant. When he rescued the girl it was effectively the same as if the daimyo himself had violated his oath and made his honor mean nothing.
• What Do You Mean, It's Not for Kids?: The animated films are in no way child-friendly, and, in some ways, are actually much Darker and Edgier than even the live-action films. Cartoon Network airing the films during the then kid-friendly Toonami block didn't help much either. To their credit, however, some of the more violent content was edited out of the film and it did air with a TV-14-V rating, with Content Warnings.
