“Bad Moms” got an A+ from mothers at a screening Thursday night in Port Washington who said the comedy about a stressed-out mom’s rebellion against the picture-perfect PTA president “surpassed expectations” and lived up to the hype.

“Very rarely do we go to the theater and laugh out loud,” said Vera Sweeney, 38, of Garden City, a mom of three children ages 3, 9 and 11. “We laughed out loud a few times at this one.”

Said her friend Barbara Massina, 45, of Garden City, who has three children, two age 10 and one age 9: “It was surprisingly great.” Both women agreed that Kathryn Hahn, who played a risqué single mom, stole the show. “She was amazing,” Massina said.

The women attended one of Long Island’s first moms-night-out gatherings — the movie officially opens Friday. Dozens of groups of moms have rented out theaters across Long Island in the coming weeks to watch the film together. The night out at Soundview Cinemas was sponsored by MomTime Events and included pulled pork sliders, quesadillas and chicken tenders with coleslaw or macaroni and cheese, catered by Wings Plus of Port Washington. The volunteer teenage servers wore T-shirts that said “Bad Daughters.”

“Since the movie is called ‘Bad Moms,’ we thought it would be funny to make a shirt that said ‘Bad Daughters,’” said waitress Danielle Elkins, 17, of Port Washington.

The event raised funds for The Safe Center LI, which provides programs and services for adults and children who are victims of abuse.

The 170-plus moms cheered several times during the film — no spoilers here, but suffice it to say they loved a hilarious scene where the moms talk about their freedom fantasies and vicariously enjoyed every time the rebel mothers just said “no” to their husbands, their kids and the over-the top demands of the PTA.

“It was an exaggeration of what real life is like at any school,” said Carlie Gehl, 37, of Port Washington, who has two kids, ages 3 and 6.

Annie Thornton, 46, of Port Washington, the mom of two kids ages 10 and 7, said she sometimes watches the trailers of upcoming movies that seem to give away all the best part of the film. That wasn’t this case this time, she said. “That was the tip of the iceberg,” she said.

Said Allison Roditi, 37, a Port Washington single mom of two boys ages 5 and 7: “I think of everyone in the theater, something in that movie happened to one of us at some point.”

Women in the audience predicted that “word-of-mom” will spread the thumbs-up for the movie and make it a summer hit.

“It was right on, and it was hilarious,” said Sara Ross, 34, a Port Washington mom of two kids, ages 5 and 3. “It was great entertainment.”
