A sentimental exploration of what fatherhood means that doesn't overdo it with the sperm gags, it's a rather charming if unexceptional dramedy.

The tone wavers between the pantomime and the mawkish and while little has been lost in translation, less still has been gained.

Alas, the hero is played by Vince Vaughn, a limited actor whose range extends from petulant to homicidal.

Flaccid as a comedy and even more limp as a heart-warmer.
