- Moderate
- The reveal of the created monster is meant to be frightening.
- The tone of the film is generally dark, and takes place in a city where everyone is meant to be evil. A large plot point is creating evil inventions to hold the world ransom.
- The scene where the villain chases Igor in a carriage while trying to shoot him with a shrink ray may be intense for young children as Igor and his friends nearly fall off a cliff. They are rescued, however.
- Some young children may find the scene where Eva the monster turns evil and starts destroying things unsettling as it is a big change from her usual, sweet nature. She does eventually return to normal, though.
- One scene features two creepy-looking genetic mutations: A man with the head of a fly and a fly with the head of a man.
