Literally nothing about that movie is child-friendly lol

You can show/tell children anything as long as there's a happy ending.

The tale is a beautiful fable (young girl uses her imagination to escape the unhappiness and violence of her real life) that would be ideal for children, but the director of the film is certainly not into making childrens films. I have an 11 year old niece who could probably just about cope with it, but my 13 year old niece definitely couldn't.

I used to own a copy of that movie. Pretty good. Also quite gorey.
Definitely not a children's movie.

I think it's a children's book as well

No I don't think it's meant for children

No! Lol
