The fourth movie in the Hotel Transylvania series relies on a straight-forward body swap: Dracula turns into an out-of-shape human while his human son-in-law Johnny becomes a giant dragon monster.
It is loud cartoon slapstick meant to keep early elementary kids giggling. It lacks the original film's voice talent (Adam Sandler did not return as Drac) and emotional heart, but it works fine as background noise on a rainy weekend.
Expect plenty of chaotic chases, a giant gerbil, and a running gag about the Invisible Man being completely naked once he turns human.
