This movie is MAJORLY intense. While it won't be understood by young kids, from when Scrooge meets Ghost of Christmas Present to the end of the movie is extremely heartfelt and emotional.
There is a scene when Scrooge is visited by a ghost who's carrying heavy chains for "eternity" as a punishment.
In a scene in the cemetery, one of the spirits shows a little child's grave to Scrooge.
In another cemetery scene, the ghost of Christmas future (played by Pete) shows Scrooge his grave and then pushes him into it, Scrooge sees his coffin, the lid opens and is full of fire symbolizing the flames of Hell.
