If you ask a certain subset of Ghostbusters fans why they're so cranky about the new reboot, they'll give you the same answer: What they really wanted was a third Ghostbusters featuring the stars of the first two movies.

You can mock these Ghostbros all you want, but it's easy to trace this obsessive wish to its source: more than a decade of wild, unfulfilled promises made by Dan Aykroyd. As early as 1999, Aykroyd was pitching a script for Ghostbusters 3: Hellbent, which would have seen the devil dealing with an overcrowded Hell by sending residents up to Manhattan. Later years saw Aykroyd hyping a series of scuttled scripts in which the old Ghostbusters appeared to "pass the torch" to a new team. (If you’re wondering what might have been, it’s pretty easy to find exhaustive breakdowns on aborted Ghostbusters 3 scripts online.)

The new Ghostbusters does feature pretty much everyone from the original movies, minus Rick Moranis (who is more or less retired from acting) and Harold Ramis (who died in February 2014). But while Aykroyd, Bill Murray, Ernie Hudson, Sigourney Weaver, and Annie Potts all made time to appear in the new movie, none of them are playing the same characters they played in the first two Ghostbusters movies. And while it's hard to sympathize with the wingnuts who have angrily dismissed the new Ghostbusters out of hand for shallow reasons, I can sympathize with the fans who had always dreamed of seeing their favorite characters busting ghosts together one last time—and are now disappointed they'll never get the chance.

So here's the good news: Even beyond the franchise-extending cartoon The Real Ghostbusters (which ran for 140 episodes between 1986 and 1991), there are two Ghostbusters sequels—featuring the original lineup of Peter Venkman, Ray Stantz, Egon Spengler, and Winston Zeddemore—that you might have forgotten about, if you ever knew they existed at all. They're just not movies.

The first—simply titled Ghostbusters: The Return—arrived in 2004. Here’s the premise:
