Coraline is one of my daughter's favorite movies and is just an infinitely rewatchable film. It's fun, mystical, and very, very creepy. One of the best parts of the film is the excellent soundtrack by Bruno Coulais. I really do believe it's one of the greatest film soundtracks I've ever heard. Check out the main theme: If it doesn't want to make you go romp through the pumpkin patch then I have nothing left to say to you.
Also, check out the track "Exploration." It's beautiful!
