This is a 2009 stop-motion animated film, based on Neil Gaiman's novella of the same name.
A summary of the novel from Neil Gaiman's website:
When Coraline steps through a door to find another house strangely similar to her own (only better), things seem marvelous.
But there's another mother there, and another father, and they want her to stay and be their little girl. They want to change her and never let her go.
Coraline will have to fight with all her wits and courage if she is to save herself and return to her ordinary life.
And a summary of the film from Rotten Tomatoes:
Coraline Jones is a girl of 11 who is feisty, curious, and adventurous beyond her years. She and her parents have just relocated from Michigan to Oregon. Missing her friends and finding her parents to be distracted by their work, Coraline tries to find some excitement in her new environment. Coraline seriously doubts that her new home can provide anything truly intriguing to her, but it does; she uncovers a secret door in the house. Walking through the door and then venturing through an eerie passageway, she discovers an alternate version of her life and existence.
This is a beautiful film, suitable both for (older) children and adults. It's available on Netflix - but not so much on other venues.
While it is based on a children's novel, the atmosphere is not at all lighthearted, and it will provide entertainment even to adult audience.
