Pretty funny. Not as great as I thought it would be but still funny.

Average, not nearly as funny as expected.

Seth Rogen is only good when he is not the star of the movie.(Superbad, 40 year old virgin, stepbrothers) When he is the star the movie blows(Knocked up, his porno movie, and Funny People.)

Very funny, great script - lots of quotable one liners.

Very entertaining, Katherine looks awesome and a great act.

for fan of 'Freaks & Geeks' and 'Undeclared'

stupid movies about birth

While Apatow's movie isn't perfect, it's still a fumbling and funny valentine to the shock of pregnancy, the reality of love and the chaos of all that comes after.

It may be a bit, um, premature to say so, but Judd Apatow's Knocked Up strikes me as an instant classic, a comedy that captures the sexual confusion and moral ambivalence of our moment.

If you want to hate on Judd Apatow's Knocked Up -- and the anti-crowd-pleaser contingent will surely ding it -- then get ready to be drowned out by the sound of laughter from the rest of us.

The likelihood of [director Judd] Apatow turning into Chris Columbus or Ron Howard seems refreshingly slight.

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.
