"This is 40" reviews are in

"This is 40," the latest film from writer/director/producer Judd Apatow, arrives in theaters Friday.

The family comedy centers around married couple Pete (Paul Rudd) and Debbie (Leslie Mann) and their daughters (Maude and Iris Apatow), who were first seen in the 2007 comedy "Knocked Up."

The film currently has a 52 percent rating on the review aggregator website Rotten Tomatoes. Most critics praised the cast but said the film itself, while occasionally funny and poignant, is uneven and long.

Here's what some of them had to say:

• "There are moments of perception and sweetness, as per usual with Apatow movies. It's just too bad the movie's trajectory is formless and jokes built around petty marital resentments sometimes fall flat." -- Claudia Puig, USA Today.
• "This is 40" isn't always hilarious, but it's ticklishly honest and droll about all the things being a parent can do to a relationship. And why it's still worth it." -- Owen Gleiberman, Entertainment Weekly.
• "This is 40" is every inch a Judd Apatow movie, from the pop culture references and potty mouths to the blunt body humor and escapist drug use. Like all the movies he's directed -- and it's amazing to think there have only been three previous ones, given his name-brand value -- it's a good 20 minutes too long. -- Christy Lemire, Associated Press.
• "Judd Apatow's instincts have rarely been sharper, wiser or more relatable than in "This Is 40," an acutely perceptive, emotionally generous laffer about the joys and frustrations of marriage and middle age." -- Justin Chang, Variety.
• "There are a lot of loose ends and a few forced conclusions. But, then again, the acceptance of imperfection is Mr. Apatow's theme, so a degree of sloppiness is to be expected. That's life." -- A.O. Scott, The New York Times.
• "It sometimes dawdles as it circles the spectacle of a marriage in flux. Yet Pete and Debbie's sparring yields some of Apatow's most personal observations yet on the feelings for husbands, wives, parents, and children that we categorize as love." -- Peter Travers, Rolling Stone.
• "As the movie goes on, the laughs are fewer and farther between, and for the last 30 minutes, not only did I not laugh, I wanted it to end so I could get back to my own boring but less precious life." -- Mary Pols, Time.
• "Even with all its ups and downs, there are more than enough bawdy laughs and truthful emotional moments to put this over as a mainstream audience pleaser during a holiday season short on good comedies." -- Todd McCarthy, The Hollywood Reporter.
