History Film / GhostbustersII

* RetCanon: Slimer was in the first movie, but wasn't given a name (the crew called him "Onionhead") and was a minor bad guy caught by the Ghostbusters. He was turned into a good guy regular character and given a name in [[WesternAnimation/TheRealGhostbusters the cartoon series]]. the first time we see Slimer in the sequel, he's hanging around inside the Fire Station headquarters chowing down on some food, implying that even the live-action guys have adopted him. The only other scene we see him in, he's shown helping Louis, which again implies that Movie Slimer, like Cartoon Slimer, is now a TeamPet.

* ThePowerOfRock: The Ghostbusters use the positive emotions evoked by good ole rhythm 'n blues to power the slime.

* ShoutOut: At a party where Ray and Winston were performing, when they asked WhoYouGonnaCall, the kids answered [[Franchise/MastersOfTheUniverse "He-Man"]].

* AnAsskickingChristmas: The film takes place in the lead up to New Year's Eve.

* DatedHistory: When the ''Titanic'' is shown arriving in port, it has a huge hole in the prow. And is in one piece rather than having split in half. [[note]]The movie came out four years after the wreck was discovered, so there's no excuse aside from RuleOfFunny. another thing to add, a behind the scenes photo shows the model actually was split in half but the perspective of the shot hit that[[/note]]

** A spectacular example - in the Manhattan Museum of Art, just as Vigo is about to possess Oscar, above the skylight looms the animate Statue of Liberty, whose torch then shatters the glass; whereupon the Ghostbusters abseil in to the rescue.

* ThisIsGonnaSuck: Hardemeyer's reaction when the Mayor overrules his advice against bringing in the Ghostbusters and demands to know where they are (and with good reason considering their visit to the Mayor's Mansion was the last time they were publicly seen). Hardemeyer knows he now has no choice, but to come clean and reveal he had the team illegally committed – which makes him indirectly responsible for this current crisis (and jeopardizes the Mayor’s Gubernatorial ambitions once it gets out the team ‘’warned’’ Lenny this was going to happen and the authorities ignored them).

** While the Mayor has little love for the Ghostbusters, he has no idea that Hardemeyer illegally committed them after their visit to the Mayor's Mansion (and that the he usurped his authority to do so). Lenny only finds out once everything goes to hell and forces the truth out of Hardemeyer. He's rightfully furious and fires Hardemeyer on the spot.

* LockedOutOfTheLoop: Attempted when Dana first approaches Egon for help after the baby carriage incident. She's fine with him bringing Ray into the investigation -- but ''not'' Peter due to their bitter falling out. They both agree...until Ray accidentally, and without thinking, lets too much slip in front of Peter. Suspicious of what his friends are up to, Peter quickly forces the truth out of Ray.

* FailedASpotCheck: Dana. She misses that the water for a bath has suddenly gone silent.

* VillainousLegacy: Downplayed with Gozer the Gozerian, as the entity's only mentioned indirectly once (and has no apperance or involvement in the narrative thanks to the team destroying the 550 Central Park West gate). That said, Gozer ''still'' casts a shadow over the film, as the team's triumphant defeat of the Destructor, ironically, is what led to the their own destruction in the interim between films (thanks to the collateral damage).
** Similarly downplayed with Walter Peck. While the EPA bureaucrat isn't even mentioned directly or indirectly (and with Jack Hardemeyer taking his place as the obstructive bureaucrat and secondary antagonist), Peck still casts his own shadow over the second film. After all, it was his efforts to shut the team down which not only nearly allowed Gozer to triumph, but which also provided the foundation for the New York authorities to do the same following Gozer's defeat.

** And when they the team ''does'' finally start to head back to the surface to get the Packs, Ray's discovery of the River derails their tactical withdrawal. They go into even further danger without their gear -- and it blows up in their faces when the River grabs Winston. Before everything goes to hell, Winston even frantically chastises Ray and Egon for forgetting all about the Packs.

* IdiotBall: Despite Vigo nearly killing Egon and Ray from afar in their own headquarters, the team (minus Peter) still goes underground into the sewers and into isolated danger -- and ''without'' bringing any of their Ghostbusting gear with them apart from the Giga Meter. Their foolishness can be partially justified in-story. First, the Packs ''are'' a burden to carry and wield under normal circumstances; taking them underground and into a confined space would be exponentially even more difficult. Second, the team's "spelunking" ''was'' only supposed to be a simple reconnaissance mission to trace the source of the Mood Slime River's flow; they didn't plan for a full-on engagement (although, again, they ''should'' have come prepared in light of what had just happened in the Firehouse mere hours earlier).

* ScrewTheRulesImDoingWhatsRight: The team violates their judicial restraining order -- the legal and financial consequences be damned -- to help Dana investigate the mystery of what happened with Oscar's carriage.
