Ghostbusters 2 (1989)

After being sued by the city for the damages they did in the original Ghostbusters, the boys in khaki are doing kiddie shows at birthday parties. When a river of slime that is actually the physical version of evil is discovered running beneath the city, the Ghostbusters are back in action. They must do battle with a wicked spirit in a painting or the entire world will fall pray to its ravaging whims. Murray is the highlight of this serviceable sequel, although MacNicol gives him a good run as the painting's henchman.
