It’s all about the zing.

If you are not up on monster speak, the term zing refers to what happens once in the life of a vampire, mummy, werewolf, etc. It’s that moment when they know they have found the one true love in their life.

In the case of “Hotel Transylvania 3: Summer Vacation,” Dracula (voiced by Adam Sandler) learns it’s possible to zing more than once as he meets the new once-in-a-lifetime love of his life during a monster sea cruise. While Dracula zings again, this third offering in the offbeat look at the world of ghouls and monsters doesn’t come close to having the same zing as the first or second offering. It’s fun, and director Genndy Tartakovsky (“The Powerpuff Girls”) knows how to keep the action moving because of all his work in television animation, but the change of approach when dealing with Dracula coupled with the setting switch leaves the production just a little light on zing.

“Hotel Transylvania 3: Summer Vacation” picks up with the getaway destination for creatures doing booming business. Things are going so well that a break is needed and the group books passage on the first monster cruise, which will take them from the Bermuda Triangle to the found city of Atlantis. The trip becomes a monster version of “The Love Boat” as Dracula does what he has thought was impossible: He falls in love again. The problem is she’s the last in the long line of Van Helsings, who have made it their life’s work to kill Dracula.

Seeing Dracula flabbergasted makes for plenty of fun because Sandler has a way of making his voice sound both commanding and confused. It’s not quite the same when his emotional confusion comes from Dracula falling in love with the captain of the cruise ship.

There’s also something a little disconcerting about the action shifting from the hotel to the ship. In the hotel, Dracula is pulled between his personal and professional problems. Once he leaves the hotel, half the angst is gone.

That being said, “Hotel Transylvania 3: Summer Vacation” doesn’t suck. It is a visual splendor, from the fun way the creatures are portrayed to the pacing. Keeping Tartakovsky as director of all three films creates a fluid sense of comedy and look.

It would have been nice if “Hotel Transylvania 3: Summer Vacation” had the same zing as past efforts. But, there’s never a love as zing-filled as the first, and it happening a second time is amazing. The third time is not quite the charmer as the others, but still offers enough laughs to keep kids plus their mummys and daddies entertained.
