Tim Burton and Henry Selick’s The Nightmare Before Christmas is a timeless, genre-bending classic, yet the message behind the movie and the character arcs require some deliberation. Jack Skellington, the Pumpkin King of Halloween Town, is in a creative slump when he sets out to steal Christmas and execute the holiday himself rather than Santa Claus. In the end, Jack sees the error of his ways, returns Christmas to Santa, and goes on being the Pumpkin King. Along the way, he realizes his love for downtrodden Halloween Town resident Sally, who has always loved him in return.
