Which movie's premise plays like another movie's premise, but in reverse?

[TMC]

For example, it can be suggested that Beetlejuice plays like the plot of the original Ghostbusters in reverse. Whereas Ghostbusters was about a group of guys getting rid of ghosts bothering the living, Beetlejuice is about ghosts who come to another ghost to help them get rid of still-living people who are bothering them.
