History YMMV / HotelTransylvania2

* UncannyValley: The Phantom of the Opera's look is a little more realistic than everyone else's cartoony dimensions.

* MemeticMutation: "Hey, dude man! I'M A DUDE MAN!"
** The sandstorm sumoning escene became used as a joke about coments that start flamewars in latin america.

** There is a single conversation that mentions that Dracula is NotSoDifferent from Dennis and used to be a very sensitive child who took way longer than normal to grow his fangs. We find out that Vlad finally made it happen by taking something Drac loved and turning it into something that terrified him, but not once is it mentioned what that thing was or how Vlad actually went about doing it. Dracula's horrified reaction to watching Vlad try to do it again with Dennis make this seem like a pretty big detail to brush over.

* BrokenAesop: The driving tension is that Dracula wants his HalfHumanHybrid grandson, Dennis, to be a vampire instead of a human. He spends the whole movie trying to bring out his vampiric side, including a DieOrFly situation, is forced to defend the mixed-species family to his FantasticRacist father, and is just about to accept Dennis for how he truly is...when Dennis turns out to be a vampire anyway.

* EsotericHappyEnding: Although the ending is perfectly happy, with the villains either being defeated or doing a HeelFaceTurn and the main characters no longer having to move away, it can feel a little off, because the only reason for the ending turning out the way it did is the coincidence of [[spoiler:Dennis turning out to actually be a vampire after all]]. So yeah, everything turned out fine, but only because the heroes got lucky in a way that contradicts the rest of the movie, [[spoiler:which up to this point was about Dracula having to accept that Dennis is ''not'' a vampire]].

* BrokenAesop: The message that the film tries to bring across is accepting people for who they are, even if they aren't what you want them to be. Highlighted by Dracula and Vlad trying to bring out Dennis's vampire powers, and them having to learn to accept the possibility that Dennis may not even have vampire powers, and later realizing that he's perfect just the way he is. However, during the climax [[spoiler: Dennis ends up unlocking his vampire powers on his own, and essentially becomes what his grandfather and great-grandfather were wanting him to be in the first place,]] which many viewers believe ruins the lesson that the film is trying to teach.

* TheScrappy: Linda. She is highly disliked by most of the fandom because of her InnocentlyInsensitive towards Mavis and monsters in general.

* AwardSnub: It's not surprising that Selena Gomez was nominated for a Kids' Choice Award for the film, but it is that Adam Sandler wasn't.

** Averted with the movie itself in the very same program, which surprisingly managed to beat out the critically-acclaimed ''WesternAnimation/InsideOut'' for the Kids' Choice Award for Favorite Animated Movie.

* Flanderization: Dracula as a character is even worse than he was in the first film. He puts Dennis in danger by tossing him off a very high tower and then blaming the camp counselor for his ignorant action of tossing him off the tower, is very insistent about making Dennis a vampire, and at one point in the film, he says that she made him babyproof the whole hotel and saying that “someone’s overprotective”. Pot calling the kettle black, much?

* BrokenBase: The now canon pairing of Mavis and Jonathan. Some think they are cute together, others, usually those who consider Jonathan TheScrappy, can't comprehend what Mavis sees in him.

** There is a deleted scene that does reveal that the thing that Dracula loved and later feared was a baby racoon.

* TheScrappy: Linda. She is highly disliked by most of the fandom because of her InnocentlyInsensitive towards MAvis and monsters in general.

* TheScrappy: Linda.

* HilariousInHindsight: The scenario for when [[spoiler: Dennis unlocks his vampire powers after seeing Winnie get knocked down by Bela]] is a lot similar to how [[Series/KamenRiderKiva Wataru Kurenai]] unlocked his Emperor form. If that wasn't enough, remember that Kiva has a vampire motif and that Dennis and Wateru both have {{Adorkable}} human fathers.

* Several viewers felt that [[spoiler: Dennis being revealed to have vampire abilities]] ruined the message, and that it would have been better if [[spoiler: he had remained human.]]

* AndYouThoughtItWouldFail: When it became obvious that the film wasn't being screened for critics, some folks began to fear a disastrous stinker, and perhaps not unreasonably, given the critical failure of ''Film/{{Pixels}}'', Sandler's other movie released earlier that year. Instead, by the time the reviews had settled over the weekend, the film's critical percentage was actually better on Website/RottenTomatoes than that of the original. (Though with rather less reviews to work with.) More importantly, the film earned the best weekend opening for any September film. (The original ''Hotel Transylvania'' was the previous record-holder.) With Halloween being the next month, it became perfect momentum to continue with.

* ContestedSequel: Some fans thought that it uses too much credit for Sandler's writing, which makes it more like Eight Crazy Nights meets The Nightmare Before Christmas.
