Even a vampire gets old at some point. And so Dracula decides to pass on his beloved hotel, where monsters from all over the world have been vacationing for 125 years, to the next generation. So his daughter Mavis should suffer the venerable facility in the future. While he’s convinced of her talent, he has doubts about her human husband Johnny. In the end, Dracula backs down and tells his son-in-law that only a monster can run the hotel. That is the law. Johnny takes him at his word, so he resorts to Van Helsing’s invention that can turn humans into monsters. In fact, he finds himself in the body of a dragon a short time later. Unfortunately, Dracula and his friends are also turned into humans.
The conclusion of the series picks up on the well-known themes that already existed in the predecessors but developed too little. While “Hotel Transylvania: Transformania” is visually convincing and one or the other successful idea is in the animated adventure, the fourth part is a sleeping pill for long stretches.
