Andy is a decent, affable guy, and it doesn't take long before we're rooting for him to be lucky in love.
The delightful Catherine Keener is perfect as Andy's GILF (Grandmothers I'd Like to Fuck) love interest.
Each member of the cast has strong comedic timing, and none of the jokes are drawn out for so long that they lose their punch.
Sadly, the kind of consistent humor delivered by this film happens too rarely.
The 40 Year Old Virgin has one foot in romantic comedy territory, and because Carell and Keener click, that aspect works as well as the raunchy stuff.
And it's also great to see a romance between two characters who are over the age of 30.
Under the expert direction of Judd Apatow (who, with Carell, co-wrote the screenplay), the humor keeps coming, and there are surprisingly few misfires.
On those occasions when a gag fails, it is quickly forgotten.
