There doesn't seem to be a thread started for this episode. Hmmm....

Anyway. I just wanted to say that as far as the plot for this movie goes,
I remember clearly when I first watched this movie at age 14 in the theater,
that the reason for them all being split up was due to there not being any
ghosts anywhere to catch.
I think that people forget that even in the first movie that they had never, ever
seen a ghost till the library scene, and that the only reason that that library ghost
was there at all was because of the "Gozer Day" approaching. As soon as they got rid
of Gozer they would NOT be able to see ANY ghost, let alone catch them, and would be
forces to go back doing whatever they were doing before. Now that they had part 2
to see, we were able to actual see them go back to there regular jobs. When the
new threat come about, and the supernatural activity is back to levels where it
can be detected by humans again, they are back in business.
Basically ts like this: The Ghostbusters live in the same world we do. If there
had been no gozer day, they  would have still been kicked out of the university
and most likely be in these jobs that they are in now, minus the Ghostbusters party gigs.
