Comic Nate Bargatze’s Hollywood studio comedy debut, “The Breadwinner,” is another “Mister Mom/Daddy Daycare” knockoff, a “Dad’s no good at kiddie caregiving” conceit that’s so moldy and out of date that the less said about this stiff the better.

But given the beatdown that Bargatze deserves (he co-wrote it) for creating this corpse, it’s worth recalling something the great comic actor David Alan Grier said about auditioning for “Seinfeld.” The pilot script “sucked.” True enough. But “This man can’t act” was the real reason Grier figured that “show about nothing” was never going to become a reality.

Bargazte can’t act. Not a lick. You stare at his flat expressions and look for signs of life behind those empty eyes and wonder how this ever got a green light. He’s Jim Gaffigan without the uh, “personality.”

Yes, but that didn’t keep Jerry Seinfeld from fame and fortune. So no sense putting one’s head in the oven about a bad review or two or seventy.

The movie Bargatze builds around his shtick has him playing “the top Toyota salesman in Greater Nashville,” Nate Wilcox, a married father of three girls “living the American dream.”

He’s married to creative and hyper-organized Katie (Mandy Moore) who keeps home and hearth together and three daughters (Stella Grace Fitzgerald, Birdie Borria and Charlotte Anne Tucker) healthy and happy.

Then one of Katie’s organizer ideas — the Starminder — gets her on “Shark Tank,” where her Big Idea might be worth the backing of the performative capitalist “stars.” If, that is, they can get past the “full time mom” problem of their potential CEO, and the “bozo” her husband comes off as when they drag him on camera — mouth full of donut — to see if he’ll pick up the slack.

One “How hard can it be?” followed by a “It isn’t surgery” and Katie’s in business — in South Korea, where they’ll manufacture the plastic do-dads.

Dad? He’s instantly over his head. He doesn’t know which schools his kids go to, has no clue about cooking, cleaning, laundry or how to open a parent-teacher “portal” to get progress reports from the girls’ schools.

“Katie, portals aren’t real.”

Ruined meals, “shortcuts,” insecurity about his place at work and a rigid schedule set up by his wife are Dad’s undoing. His kids freely admit “We’re kind of a lot.”

The sexism of the plot isn’t as grating as it might have been, and a big’ol Walmart plug mid-movie is as backhanded a slap at disposable consumerism as a lifestyle as America’s Biggest Big Box is likely to have ever signed off on.

It’s just that there’s nothing funny in any of this — cloyingly smart-aleck kids, “Shark Tankers” doubling down on mean without managing amuzing, buy-the-kid-a-pony gags, the works.

Even the incompetent roofer (Will Forte) dad hires is worth barely a chuckle.

Actors cast as random delivery guys and teachers show up and demonstrate the poor judgement of all involved when it comes to “But can he/she/THEY be funny?” Must have been some producer’s relatives.

Bargatze is just plain bad. But here’s Colin Jost of “Saturday Night Live” and Kumail Nanjiani (“The Big Sick” just as bad, showing off just how much time they’re spending in the gym these days and how little input either had on making a terrible script more tolerable.

Family friendly comedies are rare, but not so rare that there isn’t more than one idea about ways to make “Dad” funny.

“The Breadwinner” is downright embarassing, and not in a funny way. Not that it should end Bargatze’s career. Well, maybe the movie career.
