She already got two movies and a TV series out of “My Big Fat Greek Wedding.” And Nia Vardalos even put a Greek travel comedy into theaters, “My Life in Ruins.”

But it’s pretty obvious that the only thing Hollywood wants out of her is more versions of her big family comedy sleeper hit of 20 years ago. And that’s a shame, and not just because she is utterly out of ideas of what to do with those characters except send them on a trip. That’s lame enough to be a 30 year running gag on “The Simpsons.”

“My Big Fat Greek Wedding 3” is a comedy that’s almost over before it begins, a Greek travelogue and tourism ad filled with the less-funny-by-the-movie/TV episode Portakalous family one more time.

Actors have died, so patriarchs are written out. An excuse with screenwriterly stretch-marks must be trotted out to send the family to Greece. With Gus (Michael Constantine) dead, the family is making the visit to the village he emigrated from for a reunion, a trip he never got to make.

Because “immigrants work hard,” give it all to the kids,” that’s their ethos, daughter Toula (Vardalos) preaches.

She wants to fulfill Dad’s wish that his journal be handed over to his childhood friends, who’d learn how his life turned out and the glories of a big Greek American family in Chicago and a restaurant called Dancing Zorba’s.

Brother Nick (Louis Mandylor) has other plans to do with Dad’s wishes, if he can ever stop grossly “grooming” himself in front of everybody and manage it.

Daughter Paris (Elena Kampourish) has taken off from NYU to come along, but she has a secret. Aunt Voula (Andrea Martin, still stealing scenes) has hired the guy everybody wants Paris to end up with, Aristotle (Elias Kacavas) to be her luggage porter for the trip.

A last goodbye to Mom (Lainie Kazan), who is slipping into dementia, and seven of them are off to the Olde Country, to meet the hip, tries-too-hard mayor of the dying village, the non-binary Victory (Melina Kotselou).

A big family secret will turn up. They and we will see olive groves and vineyards, flocks and herds and donkeys, the sights of Greece (“Can we stop at the Parthenon?” “No.”). Cranky locals will turn out to be kindhearted when it comes to the refugees who are flooding into Greece from the Middle East and Ukraine.

“Say ‘Hello!’ We are not xenophobic!”

“GREEK word!”

Things will look bleak, but another Big Fat Greek Wedding might in the cards for somebody.

Vardalos is out of new things to say — “A Greek man retires a week after he’s dead!” “Have sex on Easter, like everybody else!” And the new characters don’t have enough screen time to blossom and make some larger statement on Greece today. There’s barely room for the usual Vardalos pleas for tolerance via a big fat Greek embrace of everybody, gender, nationality be damned.

The players vary in their commitments, from barely worth the effort to trying too hard.

The third act delivers a couple of warm moments that lift it. But this picture’s a corpse still being shock-paddled and CPR-pounded on the operating table. Call the code, Nia. And yes, you look younger than everybody else in the orignal cast, now.
