It’s 3D animation, and I believe it’s largely stop-motion, not CGI. It’s a modern fairy tale. It has a witch a and a cat and a mouse circus and retired actresses. It has a brave little girl, who rescues some other lost children (with the help of the cat and of a boy). It has a weird old house. It has food. It has flowers. It has other parents. And of course it has needles coming out of the screen right towards the audience (but not very many).
Really. Go see it.
