Hotel Transylvania 2

Hotel Transylvania 2 is a 2015 American 3D computer animated monster comedy film, the second installment in the Hotel Transylvania franchise and the sequel to the 2012 film Hotel Transylvania, with its director, Genndy Tartakovsky, and writer, Robert Smigel, returning for the film.

Plot
Now that Dracula (Adam Sandler) has opened the Hotel Transylvania's doors to humans, things are changing for the better; however, Drac is secretly worried that his half-human grandson, Dennis, isn't showing his vampire side. So, while Mavis and Johnny are away, Drac enlists his friends to help him put the boy through a "monster-in-training" boot camp. But things really get batty when Drac's cantankerous, old-school dad (Mel Brooks) pays an unexpected visit.

Good Qualities

 * 1) It still retains the charm of the first film.
 * 2) Great voice acting from the likes of Adam Sandler as Dracula (who starred in films like Hubie Halloween as Hubie Dubois, Uncut Gems as Howard Ratner, Billy Madison as the eponymous character, and Punch-Drunk Love as Barry Egan), Selena Gomez as Mavis (who also starred as Mary Santiago from Another Cinderella Story, Carter Manson from Princess Protection Program, Beezus from Ramona and Beezus, and Grace Bennet from Monte Carlo), Asher Blinkoff as Dennis (who also stars in Sing and The Jungle Book (2016)), Mel Brooks as Vlad (who also plays Victor Frankenstein from Young Frankenstein, Mel Fuun from Silent Movie, and even directed features such as Blazing Saddles and The Producers), David Spade as Griffin (who also plays Emperor Kuzco from The Emperor's New Groove, Eli Turnbull from Coneheads, and Richard Hayden from Tommy Boy), Keegan-Michael Key as Murray (who also plays Frank the Foreman from The Lego Movie, Judge Peckinpah from The Angry Birds Movie, Ducky from Toy Story 4, and Hugo Gernsback from Tomorrowland), Steve Buscemi as Wayne (who also plays Theodore Donald Kerabatsos from The Big Lebowski, Randall Boggs from Monsters, Inc., and Templeton from Charlotte's Web (2006) and Andy Samberg as Johnny (who also plays Baby Brent from Cloudy with a Chance of Meatballs and Nyles from Palm Springs).
 * 3) The animation is still great, with more fluid movements and brighter colors than the first film.
 * 4) Great soundtrack.
 * 5) Some funny lines like "Nutsy koo koo", "Screaming's not helping", and the Bluetooth joke. Not to mention Drac's returning quote from the first film "I don't say bleh, bleh, bleh!"
 * 6) The new characters are great. Dennis is a likable and cute character who can be considered sympathetic due to being different from his mother and grandfather and trying to fit in and Vlad is also entertaining.
 * 7) It delivers a good message about how we should accept others for who they are. While it is a bit impaired by the revelation that Dennis was actually a vampire all along, it's still manages to be here and gets the message to the audience.
 * 8) Like the first film, the end credits sequence uses 2D animation in the veins of Genndy's TV cartoons such as Dexter's Laboratory.
 * Dennis discovering his vampire side is well written.

Bad Qualities

 * 1) There is a continuity error in one scene, Mavis and Dracula are invisible in the pictures, but somehow in a later scene Mavis has a profile picture on Dracula's cellphone and also somehow Dracula and Mavis can face time on their cellphones but yet they can't be seen when a picture is taken.
 * 2) Just like the first film, it has some toilet and fart humor.
 * 3) Some product placement is shown like Sony cellphones (even though it owns Columbia Pictures and Sony Pictures Animation, which the film is distributed by), Facebook and YouTube (although the latter scene is pretty funny).
 * 4) Although Keegan-Michael Key does a good job as Murray, he lacks the charm that CeeLo Green had from the first movie (although he had to replace Green since he was running into legal issues).
 * 5) Depending on your view, Dracula is sadly flanderized in this film, as he does some really scummy things such as lying to his daughter and nearly killing his grandson (though the latter was an accident). Although his motivations were slightly understandable due to wanting Dennis to become a fully-fledged vampire. But he learns his lesson and still cares for his family.
 * 6) *Dracula's daughter, Mavis also flanderized herself when she became a mother to Dennis when her anger, while funny and serious, is a big failure of portrayal making her behave more like an unlikable drama queen.
 * 7) The film's message of accepting others for who they are and not for who we want them to be feels somewhat diminished at the end when it's revealed that Dennis has inherited vampiric powers after all despite the film making it look like he lacked them and that Dracula should accept that his grandson was not a full vampire.
 * 8) The main villain, Bela, is rather weak and minor. This is due to him getting less than ten minutes of screentime.

Reception
