Metacritic reviews

Ultimately, what makes Knocked Up a terrific film--one of the year's best, easily--is its relaxed, shaggy vibe; if it feels improvised in places, that's because Apatow trusts his actors enough to let them make it up as they go, like the people they're playing.

The very opposite of a storybook romance, and also the very model of a great comedy for our values-driven time.

Believe the hype, Knocked Up is one of the funniest films of 2007. It's too early in the year to crown it the supreme funniest title, but save for something so funny your head explodes in the theater, I think it'll take the title by year's end. Seth Rogen, we web slackers salute you!

Knocked Up could be one of the summer of 2007's sleeper hits. It certainly deserves the distinction.

Rogen and Heigl step up to the plate with a tougher task from Coach Apatow: Nail every laugh and the emotions underlying them. No worries. They knock it out of the park.

Knocked Up feels very NOW. The banter is bruisingly funny, the characters BRILLIANTLY childish, the portrait of our culture's narrowing gap between children and their elders hysterical--in all senses.

On the surface, Apatow's films are about sex--obsessively, exclusively, and exhaustively. (This one lasts more than two hours.) But that is a clever feint, for their true subject is age.

Line for line, Knocked Up isn't quite as funny as "The 40-Year-Old Virgin," which got most of its laughs from the friction between prissy Carell and his sex-crazed stoner co-workers. But it is equally good as a nutty anthropology of marginal living and as an illustration of how much energy it takes to do nothing in a work-obsessed society.

Most of the movie feels like a loose, sometimes improvised lark among friends.

Like most of Apatow's work, Knocked Up walks a perilous line between sarcasm and sentimentality, and though it's extremely funny in bursts, the movie flirts once too often with schmaltz before toppling into melodrama in its third act. The fault lies as much with Apatow's casting as his writing.
