One of the best movies of the 1980's, and later went on to spawn an immensely popular cartoon series (some claimed it equal in popularity to the later
Teenage Mutant Ninja Turtles in the early 90's), and later an equally entertaining sequel. Then, in the
mid-90's, a spin-off cartoon series was released in hopes of reviving
the franchise (entitled "Extreme Ghostbusters"), but was nowhere near as good as the original.
