If you're ever invited to the Apatows, you may want to politely decline.

That's because, based on writer-director Judd Apatow's "This Is 40," filmed in and around his Four Season hotel interior decor-styled Los Angeles area home, you will be subjected to a barrage of rude, lewd and crude invective, diatribes and behavior.

"This Is 40" is an often desperate attempt at comedy. I found the movie mostly insufferable. "This is 40" is Judd Apatow's home movie.

"This Is 40" stars Apatow's wife, Leslie Mann, portraying Debbie, wife of Pete (Paul Rudd). Pete and Debbie are characters Apatow introduced in his movie, "Knocked Up" (2007), which he also wrote and directed.

As that title suggests, Apatow leaves little to the imagination in his take on domestic life more like domestic dysfunctionalism relationships and business associations in these United States.

"This is 40" is akin to group therapy. Let the Apatows do couples counseling. Just don't charge admission. Look at the poster for "This Is 40" and you will see Apatow is pushing crudeness in the public's faces.

The thin plot line of "This Is 40," which has the sense of a home movie but on a Hollywood studio budget, has to do with Pete and Debbie's marriage, suffering from wear and tear; a boutique where Debbie suspects one of her employees (Megan Fox, Charlyne Yi) is stealing money; and the struggling indie record label Pete hopes to revive with a Graham Parker and the Rumor reunion concert and CD.

The movie's run time, at two hours and 14 minutes, which is generally too long for a comedy, is only one of the structural defects with "This Is 40." The other is Apatow's "quip-cut," to coin a cliche, directorial technique, in which scenes shamble to a wrenching conclusion with a presumably funny retort.

Apatow includes Hollywood insider jokes in the dialogue, referencing TV's "Lost" producer J.J. Abrams and movie star George Clooney, although one wonders how pleased the actor will be with his last name becoming a verb for permanent bachelorhood, as in: "You could Clooney it."

Also bearing the brunt of Apatow's jokes besides his family and himself (as Rudd), for that matter, is Graham Parker, for whom this potential career-boost movie role comes off as more of a career-ender.

Mann has a propensity for ending her line readings with an "up" intonation.

Rudd is his usual affable self.

In a small role, Jason Segel is the same puppy-dog character which he usually plays. Albert Brooks and John Lithgow appear in supporting roles with the concentration of actors awaiting the next call from their agents.

Apatow's casting of his and Leslie Mann's daughters, Maude and Iris, as Pete and Debbie's daughters, Sadie and Charlotte, in scenes with ear-burning content, could be considered to border on child abuse.

"Funny People" (2009), the last feature Apatow directed, wasn't very funny. "Knocked Up" and "The 40-Year-Old Virgin" (2005) were funnier because those movies were actor-dependent, with Seth Rogen, Steve Carell, a co-writer on "The 40-Year-Old Virgin," who each have intriguing nebbish vulnerability. Rudd and Mann simply can't carry "This Is 40."

This is not entirely Mann and Rudd's fault. Apatow doesn't give them much to work with. It's obvious Apatow depended a lot on the actors' improv abilities and chose alternate takes.

Apatow's approach to screenwriting and film-making seems to be that of "Wouldn't it be funny if we did this?" Well, yes, and no. "This Is 40" is Woody Allen without the wood.

Apatow seems intent on turning the phrase "as American as motherhood, Apple Pie and Chevrolet" into "as American as obnoxious people, 'American Pie' and BMWs."

"This Is 40" is "American Pie" for fortysomethings. If that's your taste in movies, as they say in all the best diners: "Enjoy!"
