Writers Rick Elice and Marshall Brickman have come up with an original story, and have tried to give every cast member the chance to deliver a quick quip - even ghoulish manservant Lurch, who manages to get the audience to laugh by simply grunting. The show is corny and crazy, but that's part of its charm.
A discordant stage is set when we meet full-of-woe daughter Wednesday (the vocally gifted Teagan Wouters) who is uncharacteristically full of love for Lucas Beineke, played by New Zealand's Tim Maddren.
She tells father Gomez that Lucas has asked her to marry him, and she's invited him and his parents to dinner.
She begs her macabre family to act "normal" and gets Gomez to promise not to tell mother Morticia (Chloe Dallimore) - who detests happiness, loves pulling the heads off flowers and embraces the thought of death being around the corner - about the planned marriage.
Here's where the problems begin. Gomez has never kept a secret from Morticia, whom he adores and looks forward to taking to the bedroom at least twice a day. Morticia, who wears a gown with its neckline "cut down to Venezuela", realises something is not normal. So, too, do Lucas' parents, Mal and Alice Beineke, played by Tony Harvey and Katrina Retallick.
"Do you have a little girls' room?" asks Alice Beineke when she and her husband arrive at the gothic house in Central Park. "We used to," says Gomez, who likes to collect weapons of torture, "but we let them all go."
Gomez, played by class actor John Waters who boasts countless television, film and theatre credits, steals the show with his one-liners, complete with the lively Spanish accent.
He's not a bad singer, either, entrancing the crowd with his solos Trapped, Happy/Sad and Not Today.
While Morticia gives him the cold shoulder, we learn during dinner - when the cast sings the brilliant number Full Disclosure - that all is not rosy in the Beineke camp either. Pugsley (Blake Hurford, one of five different boys that play the role) accidentally gives Alice Beineke a truth poison instead of his sister, and she sings after supper.
Poor Pugsley is desperate for Wednesday to fall out of love so she'll spend more time torturing him and being mean again.
That four-letter word is also a problem for Uncle Fester (Russell Dykstra) as he contemplates how to become one with his new love, the Moon. The show's special effects are put to good use in The Moon and Me, as Fester floats above the stage crooning.
Along with the levitation tricks, the set is impressive with good use of the curtain, while Andrew Lippa's musical numbers embellish this wacky show with a mix of tango, ballads, pop, vaudeville and Broadway.
Love conquers all couples by the end of the show, which ends with one of the best-known lines from Addams' cartoons, when Gomez promises to fulfill his wife's dream of visiting the Paris sewers. "Are you unhappy, darling?" he asks.
"Oh yes, yes! Completely," Morticia gushes.
Whether you're an Addams Family fan or not, you're going to hate (love) it.
