This is 40 -- and it's pretty funny

Judd Apatow puts a toe into mature waters, but doesn't forget to bring along the laughs.

It takes a long time to get to her, but when the new Judd Apatow comedy, This is 40, arrives at a scene that's stolen by Melissa McCarthy, the humor suddenly becomes incendiary, foul-mouthed and very funny. Building on the crudeness she established in Bridesmaids, McCarthy scores big -- so big, in fact, that writer/director Apatow had the good sense to include one of her character's rants in an outtake.

But I digress, even before I begin.

In this mostly enjoyable outing, Apatow casts Paul Rudd and Leslie Mann (Apatow's real-life wife) as a husband and wife who also happen to be the self-absorbed parents of two daughters (Apatow's real daughters, Maude and Iris). Rudd's Pete runs a Los Angeles-based record company devoted to indulging his passion for '70s rock. Mann's Debbie owns an upscale boutique. And, yes, This is 40 represents a reunion for Rudd and Mann, both of whom appeared in Apatow's 2007 comedy, Knocked Up.

Of course, Pete and Debbie are way past knocked up. They're deeply ensconced in the grind of family life. Over the years, their relationship has lost a good deal of its romantic luster. Not surprisingly, Pete and Debbie have issues -- not the least of which revolves around the financial help Pete gives to his father (Albert Brooks), a likable freeloader who has started a new family.

A sharply funny Brooks -- who immediately raises the movie's comic ante -- plays an older man married to a younger woman and now grappling with three young children. Long on gall, Dad views any resistance by Pete as evidence of his son's selfishness. Never mind that Pete has financial troubles of his own.

Perhaps to balance things, Debbie's father (John Lithgow) enters the picture, as well. He's also married to a younger woman, and has been estranged from his daughter for years.

As the movie progresses, Lithgow's character sheds the bonds of caricature and becomes a real, flesh-and-blood father. Credit Apatow with mixing some expectedly crude humor (not all of it funny) with a few well-played scenes in which the writer/director makes a welcome journey into adult territory. Hey, at least he's putting a toe in deeper waters.

Unlike a comedy such as The Guilt Trip, This is 40 is no anemic two-hander. Apatow not only makes room for Brooks and Lithgow, but for Jason Siegel (as an overly confident physical trainer), Graham Parker (as a musician who can't sell any of his new recordings), Chris O'Dowd (as one of Pete's employees) and Megan Fox (as a woman who works in Debbie's boutique).

That's a decent amount of support for a comedy that aspires to be attuned to the debilitations of middle-age, many of them shockingly trivial. Pete is a little too fond of cupcakes. Debbie likes to sneak cigarettes. In this sun-splashed and mostly prosperous LA world, what could be more sinful than overeating or doing something that poses a direct threat to robust good health?

At 134 minutes, This is 40 probably overstays its welcome, and no one's likely to confuse it with Ingmar Bergman's Scenes from a Marriage, which Apatow reportedly watched before making his movie. OK, so Apatow isn't making great art, but, then again, Bergman didn't get many laughs, either.

With friends like these ....

A trendy sitcom of a movie substitutes banter for real depth.

Call me old-fashioned, but I still cling to the expectation that movies should to be richer, bigger and more emotionally savvy than anything that's available on TV. While watching Friends With Kids, a rom-com from director Jennifer Westfeldt, I couldn’t shake the feeling that I had tuned into a sitcom made by a writer/director who was well-versed in the distressingly insular language of contemporary relationships.

Westfeldt's movie feels smart in the way that sit-coms sometimes feel smart; it's almost as if issues are being referenced rather than explored.

Like most rom-coms, Friends With Kids springs from a contrivance. Two friends (Westfeldt and Adam Scott) are wary of the pitfalls that can sabotage sustained relationships, but want to become parents anyway. So, they decide to avoid the problems faced by their friends with children and have a kid without the burden of also having a romantic relationship. Because they're not sexually attracted to each other, they think it should be easy to have a kid, share parenting chores and otherwise get with their lives. It helps that they live in the same Manhattan apartment building.

For the most part, the movie's more traditional couples are accessories that support the main endeavor. Maya Rudolph and Chris O’Dowd play a husband and wife who fight all the time because they're both constantly frazzled about the demands of child-rearing. Jon Hamm and Kristen Wiig play another couple. Their marriage buckles because of the strains placed on it by his womanizing.

Not surprisingly, the married couples think that Westfeldt’s Julie and Scott’s Jason have lost their minds. They think it's a mistake to have kids without a formal relationship, but at least in the beginning, Julie and Jason seem to have made a wise choice. They're super-tolerant of each other’s dating lives, and they split the demanding chores of caring for an infant.

Westfeldt (co-writer and star of Kissing Jessica Stein) keeps the tone reasonably light, as she examines the dating lives of Julie and Jason. A beefy looking Ed Burns shows up as a a possible beau for Julie; he’s a generally nice guy who’s divorced and has kids of his own. Jason falls for a sexy dancer (Megan Fox) who’s very clear about having no interest in a traditional relationship or in having kids.

About three-quarters of the way through, Westfeldt shifts the movie's tone. At a dinner on a Vermont ski trip the friends take together, Ham’s character has too much to drink and launches into a sneering tirade about Julie and Jason, predicting that their arrangement ultimately will crumble.

True to form, it does, and the movie stops being a trendy look at contemporary lives and love, and becomes a traditional rom-com that poses a distressingly predictable question: Will Julie and Jason become a couple?

I watched Friends With Kids without being bored or totally put off, but things never really deepen in ways that feel emotionally right.

One footnote: I won't give anything away, but the last line of the movie is needlessly coarse, a turn-off just at the moment when Friends With Kids could have used a little glow.
