Ghostbusters

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.
