Some viewers consider that violence realistic enough to stop watching altogether. The arrow-head's impact with the marauder's hilt rips his arms off. Ashitaka attempts to disarm a Ronin who is about to kill a peasant by shooting his sword out of his hands, only for his cursed arm to 'aid' him by imparting supernatural strength.Touch one, and your features melt into squirming black glop. The Tatari-gami, the creatures turned into worm/tentacle monsters by hate, look as toxic as they are.And then there's Okkoto, who is eventually to suffer the very same fate. As he dies, we get a close up of his face, as his flesh is melting from his bones. The very first scene features Nago, a giant boar that is covered by crawling worms and destroying everything in his path.Unfortunately, it does get watched by viewers much younger than its target demographic.
Princess Mononoke is extremely intense and was not intended for children.
